A candidate is the fermionic ^6Li atom. Evaporative cooling of a spin-polarized ^6Li gas, however, is not possible due to the absence of s-wave collisions. One solution to this problem may be sympathetic cooling: the ^6Li atoms are cooled by contact with an ultracold bosonic ^7Li gas. Another option could be the use of coexisting ^6Li samples in different hyperfine states.(e.g. Stoof et al., Phys. Rev. Lett. 76), 10 (1996). To enable an evaluation of these solutions, we present calculated values for the scattering lengths and exchange decay rates for all relevant cold ^6Li--^7Li and ^6Li--^6Li collisions. These quantities are also of interest for possible experiments with coexisting quantum-degenerate phases of ^6Li and ^7Li. In this connection we predict Feshbach resonances for ^7Li--^6Li collisions. Also, we present the scattering length and exchange decay rate for ^7Li |f=2,m=2>--^7Li |f=1,m=-1> collisions which determine if coexisting ^7Li Bose condensates can be realized. Our predictions are based on recent rigorous values for the dispersion coefficients and improved knowledge of the short-range interaction extracted by us from recent photoassociation and two-photon data.(E.R.I. Abraham et al., Phys. Rev. A 53), R3713 (1996).

We predict positive scattering lengths for the 39 Kϩ 39 K and 41 Kϩ 41 K singlet potentials, as well as for the 41 Kϩ 41 K triplet potential, and a negative value for 39 Kϩ 39 K triplet scattering. From a study of the magnetic field dependence we conclude that 41 K may be a bosonic atom with a Feshbach resonance in the magnetic field range where these atoms can be trapped in the f ϭ1, m f ϭϪ1 hyperfine state, thus providing a possibility to switch between stable and instable condensates in a Bose-Einstein condensation experiment.

This means that applications can access core network functionality by means of open standardised APIs based on open technology. One value of opening up of the network is the emergence of new business models where applications can be developed and provided by enterprises outside the traditional network operator domain. Combined with the fact that applications can be built with standard IT technology and tools, new innovative applications will hit the market with development cycles shorter than ever shown before. This paper provides an overview of the Parlay / OSA initiatives on the specification of a set of open, standardized APIs. Furthermore, the paper outlines some architectural aspects that are implied and implicitly contained in the Parlay / OSA specifications, but are nevertheless critical for understanding the implications when opening up the network by means of Parlay / OSA. The paper concludes with a characterization of applications that can be built using Parlay / OSA.
