Abstract
Long-lived 10+ isomers in 122Sn and 124Sn have been identified among the products of 124Sn+325 MeV 76Ge collisions. The measurements virtually complete a series of B(E2) determinations for (νh11/2)n states in 116-130Sn, which pinpoint half filling of the νh11/2 subshell very close to N=73. Results for these Z=50 isotopes and for the N=82 isotones are contrasted, and an enlightening comparison between the effective E2 charges observec in tin and lead isotopes is developed.
