Abstract

The 160Gd(9Be,Î±3n)162Dy reaction has been used to study high-spin states in 162Dy. Pulsed beam conditions were utilised for enhanced isomer sensitivity. An isomer at 2188.1(3) keV with a half-life of 8.3(3) Âµs has been discovered and assigned KÏ€= 8+ with a 2-quasineutron configuration. Among eleven Î³-ray decay branches, an E2, âˆ†K= 8 transition to the ground-state band was observed with a reduced hindrance of fÎ½=35, agreeing well with systematics correlating fÎ½ with the product of the valence neutron and proton numbers (NpNn) over an extended N, Z range. Small deviations from NpNn dependence are analysed for a range of 2-quasiparticle isomer decays, and interpreted as arising from a weak dependence on the isomer excitation energy relative to the yrast line.
