Description

Reaction products of 122,124Sn + 76Ge(8OSe) collisions 10--15% above the barrier have been studied by γ-ray spectroscopy, and new yrast isomers in 119--124Sn isotopes have been identified and characterized. B(E2) values determined for (νh11/2)n 10+ → 8+ transitions in even-A Sn nuclei pinpoint half-filling of the νh11/2 subshell close to N = 73. In odd-A Sn isotopes, 19/2+ isomers with 1--10 μs half-lives occur systematically, and higher-lying (νhll/2)nv=3 27/2- isomers in 119Sn and 121Sn have also been identified. These deep inelastic excitation processes were found to populate a large number of neutron-rich nuclei strongly enough for yrast spectroscopy studies
