Abstract

The distribution of magnetic dipole transition strength in Sn120 has been measured at excitations between 7.3 and 9.3 MeV using highly polarized tagged photons. A total M1 strength of eV corresponding to B(M1)=8.8-0.9+1.102 was found to be more or less uniformly distributed throughout the region. This result and previous polarized photon measurements in Zr90 and the Pb nuclei present a consistent picture of M1 strengths in closed-shell nuclei in terms of the required normalization for the spin nucleon g factors. Normalizations with respect to the bare nucleon values are 0.680.02 and 0.640.03 for the proton and neutron spin g factors, respectively.
