Abstract
A new high-spin isomer in 215Bi, with a half-life of 36.9(6) s, has been identified at the PSB-ISOLDE on-line mass separator using the pulsed-release technique combined with the element selective RILIS source. A decay scheme of 215mBi was constructed and complemented with the low-spin structure observed in 215gBi decay. The population of a cascade on top of the (νg9/2)9/2+5 level in 215Po provides evidence for Gamow-Teller β-decay of the high-spin 215Bi isomer.
