Fusion evaporation recoils were selected using the gas-filled spectrometer, SASSYER. Delayed γ-rays, following isomeric decays, were detected at the focal plane of SASSYER with a small array of HPGe detectors. Transitions following the proposed Jπ ≤ 8+ isomers were observed, and the half-lives measured. The experiments are discussed and results compared to expectations from the seniority scheme.enIsomers and seniority in the trans-Pb nuclei2005-10-0110.1088/0954-3899/31/10/04125444498596
