Abstract

Isomeric states in isotopes in the vicinity of doubly-magic ²⁰⁸Pb were populated following reactions of a relativistic ²⁰⁸Pb primary beam impinging on a ⁹Be fragmentation target. Secondary beams of ^{198,200,202,206}Pb and ²⁰⁶Hg were isotopically separated and implanted in a passive stopper positioned in the focal plane of the GSI Fragment Separator. Delayed γ rays were detected with the Advanced Gamma Tracking Array (AGATA). Decay schemes were re-evaluated and interpreted with shell-model calculations. The momentum-dependent population of isomeric states in the two-nucleon hole nuclei ²⁰⁶Pb/²⁰⁶Hg was found to differ from the population of multi neutron-hole isomeric states in ^198,200,202Pb.
