Isomeric and ground-state decay of $^{215}$Bi

A new high-spin isomer in /sup 215/Bi, 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 /sup 215m/Bi was constructed and complemented with the low-spin st...

Descripción
Sumario:A new high-spin isomer in /sup 215/Bi, 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 /sup 215m/Bi was constructed and complemented with the low-spin structure observed in /sup 215g/Bi decay. The population of a cascade on top of the ( nu g/sub 9/2/)/sub 9/2+//sup 5/ level in /sup 215/Po provides evidence for Gamow-Teller beta -decay of the high-spin /sup 215/Bi isomer. (15 refs).
