Such a shift back was based upon two sites (Tel Yarmouth, Megiddo) which were the backbone of the " reform, " but actually do not offer complete sequences for the whole EBA. This was the weakest stone of the revision, together with a partial understanding of stratigraphy/contexts from where samples were taken. Tell es-Sultan/Jericho in Palestine was included in this study, as this prominent archaeological site provided well stratified 14 C dates for EBA. Its stratigra-phy, established by Kathleen M. Kenyon in the 1950s, was reappraised by the Sapienza University of Rome–Palesti-nian MOTA-DACH joint Expedition (1997–2018). Published 14 C dates were reanalyzed along with new samples from carefully stratified and published archaeological contexts, measured by the CEDAD Laboratory (University of Salento, Lecce, Italy). They provided absolute dates connected with stratigraphy useful to double-check the proposed High Chronology. EBA stratigraphic periodization at Jericho suggests a more cautious approach and keeps a multi-based chronology more consistent with a comprehensive historical reconstruction of the Early Bronze Age in Syria-Palestine and Egypt.

This uncertainty is mainly due to the lack of primary sources and certain dating issues. By combining dendrochronological analysis and radiocarbon dating, some light was shed on the building’s history. Open at least from 897, in 1059 Pope Nicholas II re-consecrated the baptistry after several renovations. Around that period, the octagonal dome was probably built by using chestnut beams to tie the structure together. The dendrochronological analysis dated the silver fir element to 1268. This element possibly represents a replacement coincident with the period, between 1270 and 1300, when a substantial part of the mosaics of the dome was positioned.

We present the results of the AMS radiocarbon dating analyses carried out on the organic remains extracted from the casting cores of the Riace bronzes, among the most famous and well preserved sculptures of the Greek-Classical period. Although different dating hypotheses have been suggested on the base of stylistic considerations, no conclusive answers are, so far, available. The sample selection and preparation protocols of the different kind of organic materials (charred wood, vegetal remains and animal hairs) are described as well as the interpretation of the results in the frame of the current dating hypotheses and available analytical information about the casting technology.

It is able to accelerate plasma ions towards substrates by means of a polarized accelerating gap. A pulsed excimer laser, KrF, was utilized in producing plasma by target ablation. A laser pulse energy of 70 mJ was focused onto different solid targets by a 15 cm focal length lens, obtaining an irradiance of about 3.5 × 108 W/cm2. To overcome plasma effects, such as arcs, usually occurring during the extraction phase, an expanding chamber with a hole in its end, was developed. To realize implantations, Si substrates were placed in front of the ions extracted by the plasma. The implanted samples were characterized by Rutherford backscattering spectroscopy, energy dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy and laser ablation combined to inductively coupled plasma mass spectrometry. Implantations of Al, Cu and Ge were achieved up to 80 nm at a relatively low accelerating voltage, 40 kV.

Measurements appear to support other archaeological evidence and have shown that 2 distinct phases of human occupation of the site can be identified: the first occupation in the Early Neolithic and a second occupation in the Middle-Late Neolithic. The results provide new information and are a fundamental contribution to the definition of the absolute chronology of the Middle-Late Neolithic in this part of Europe.

Nevertheless, the combustion of waste leads to significant CO2 emissions in the atmosphere which, depending on the fraction of biogenic and fossil materials, have to be only partially accounted for the national greenhouse gas inventory. For this reason the development of proper methodologies for the measurement of the biogenic fraction in the combusted waste is an active research field. In fact the determination of the radiocarbon concentration in the carbon dioxide stack emissions allows to have a direct indication of the biogenic component in the burned fuel. We present the results of the AMS radiocarbon analyses carried out on carbon dioxide sampled at the stack of three power plants located in Northern Italy burning natural gas, landfill biogas and SRF (Solid Recovered Fuel) derived from MSW (Municipal Solid Waste). The sampling apparatus and the applied processing protocols are described together with the calculation procedures used to determine, from the measured radiocarbon concentrations, the proportion of biogenic and fossil component in the flue gas and in the combusted fuel. The results confirm the high potentialities of this approach in the analysis of industrial CO2 emissions.

A total of 286 bone fragments were excavated at the scene and an osteological analysis was carried out by two forensic pathologists, one of which had a anthropological background. A forensic odontologist was also involved to ascertain the completeness of the skeletons and to make an inventory of the skeletal material. It was hoped also to establish a cause of death and period in which it occurred, and if possible to attempt to identify the individual. Age and odontological assessment was also provided. This report will highlight the contribution of an odontological and radiological analysis in relation to fragments of maxillary bones with teeth in situ, and also with teeth lost post-mortem. Findings from morphological, dental and radiological examination, UV illumination in the compact bones and radioisotope scan ( 14 C) revealed these skeletal remains belonged to at least three separate individuals, dating between 600 and 1000 AD, and therefore having archaeological significance.

The age of the artefacts has been also indirectly determined by carrying out AMS radiocarbon analyses on short lived organic materials archaeologically associated with the studied objects.The measurements confirmed that the artefacts were formed by a native alloy with a gold concentration ranging from 83.10 to 88.51 wt%. The compositional homogeneity of the artefacts seems to confirm the hypothesis of a common metalworking and origin of the raw materials.

The aim of this work is to test the potentialities of carbon stable isotopic content of AMS-dated archaeological plant remains as tool to infer variations in rainfall/temperature regimes. The results obtained in the analysis of the carbon stable isotopic content of 10 plant remains selected among the archaeobotanical remains collected at the archaeological site in Faragola (Apulia, Italy) and radiocarbon-dated by AMS are presented. The variation of δ13C values was considered on a chronological scale covering a time range comprised between the II century BC and the VII century AD. The obtained patterns were also compared with local and global-scale palaeoclimatic records.

The system consists of a gas handling line and a graphite target production system. Results of AMS measurements, stable isotope mass spectrometry measurements, and gravimetric/pressure yield determinations have been used to find the proper conditions for the graphitization process. We have also investigated the 14 C contamination and the memory effect of the system during the graphitization processes. This paper covers the details of these experiments and a discussion of the results.

The analyses show, for both species, significant anomalies in the radiocarbon age due to the possible presence of a 14 C-depleted source of carbon in the formation of the shell aragonite. The magnitude of the age anomaly was quantified in the studied area to ~1000 14 C yr.

Here we present three cases where in air IBA methods were involved for the elemental characterisation of objects found in archaeological contexts, chronologically defined on the basis of high resolution AMS14C measurements. In particular we report on the identification of cinnabar (HgS) on Neolithic bones, the compositional analysis of a set of golden artefacts dated at the final Bronze age, and the analysis of red decorations on Neolithic pottery.

The sample preparation laboratory of the CEDAD (Center for Dating and Diagnostics) of the University of Lecce is developing a quality control protocol for bone samples based on Fourier transform infrared (FTIR) spectroscopy to identify the presence of collagen in bone samples and to assess its quality. FTIR measurements were carried out on collagen extracted from many ancient samples dated at CEDAD. Efforts to shift the FTIR quality control test from the filtration step to a check-in treatment are proceeding to optimize the time for preparation and to reduce the overall turnaround time. A standard fast demineralization treatment was set up and applied to a variety of ancient samples of different origin and age.

The amount, the energy and the charge state of the ions emitted from the laser-produced plasma are analyzed by time-of-flight measurements performed with the use of ion collectors (ICs) and an electrostatic ion energy analyzer (IEA). Energetic Ge ions emitted from the laser-produced plasma were directly implanted into C substrates placed at 30 cm distance from the target and 30° angle with respect to the normal to the target surface. The implantation depths and implanted doses were analyzed by two different techniques: the Rutherford backscattering spectrometry (RBS) and the laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS).
