ABSTRACT Theoretical oscillator strengths for transitions between the even 4s24p2 and the three odd (4s4p3, 4s24p4d, 4s24p5s) configurations of As+ are reported. Both ab initio, multiconfiguration Hartree-Fock and semiempirical configuration interaction techniques are used. The uncertainty of the results are estimated, by considering the reproduced energy structure, the agreement of results from the two methods and cancellation effects in the transition elements. For the strongest transitions the estimated uncertainty is about 10%.
