Abstract

Newsub-μs isomers have been observed in the neutron-rich Sn isotopes. 125,127,129Sn nuclei have been produced in a relativistic fission reaction of 238U on a 9Be target at 750 A·MeV and by the fragmentation of 136Xe at 600 A·MeV populating high-spin yrast states. In addition to the already known μs isomers, three new ones with sub-μs half-lives have been observed. These yrast isomers are the high-spin members of the ν(d−1 3/2h−2 11/2) and νh−n 11/2, seniority v = 3 multiplets leading to isomeric (23/2+) and (27/2−) states, respectively. Added to the already known 19/2+μs isomers in this region the current work completes the systematic information of neutron-hole excitations toward the filling of the last h11/2 orbital at N = 82. The results are discussed in the framework of state-of-the-art shell-model calculations using realistic interactions.
