The neutron-deficient isotope 189Bi has been studied at the University of Jyväskylä
using alpha-decay, isomer and prompt gamma-ray spectroscopy. The structure of
189Bi can be understood by the coupling of an unpaired proton to the 188Pb core,
in which spherical, prolate, and oblate shapes were found to coexist. Improved data
on alpha-decay and prompt gamma-ray spectroscopy have been obtained, giving
urther insight into the shape coexistence phenomenon in the neutron deficient lead region. |
