摘要:

Prompt and delayed &ggr; rays from in191,193Bi have been identified using the recoil‐decay tagging (RDT), isomer tagging, and recoil gating techniques, resulting in extensive level schemes for both nuclei. Excitation energies of the isomeric 13/2+states have been established and rotational bands based on them have been observed. The nearly spherical 9/2−ground‐state bands appear to be crossed by more deformed low‐lying structures. TRS calculations have been performed and B(M1)/B(E2) ratios have been extracted for the observed strongly‐coupled bands. In193Bi, a 3 &mgr;s isomer has been interpreted as ah9/2proton coupled to the 12+state of the192Pb core. © 2003 American Institute of Physics
