Effective g factors and proton-boson numbers in the vicinity of proton subshell closures

Abstract New experimental results on g factors of 21+ states are analyzed together with existing data in the Ba-Dy region. It is shown that a simple relation, based on constant values of the proton and neutron boson g factors can describe a broad range of nuclei. Moreover, the extracted values yield a much improved description of the B(M1) strengths to the newly discovered collective isovector excitations in the rare earth region. The anomalous values of g(21+) that occur in the region of the Z = 64 subshell closure are then described in terms of changes in the effective number of proton bosons Nπeff which take part in the collective motion, and the deduced values of Nπeff are compared with recent microscopic calculations. A similar approach is used to predict g(21+) values in the region of the Z = 40 subshell near A = 100.
