Abstract

A search for the population of superdeformed (SD) states in [sup 194]Pb following the [beta][sup +] decay of [sup 194]Bi was performed with the UNISOR on-line isotope separator at the Oak Ridge National Laboratory. The [beta] decay of [sup 194]Bi, with its large [ital Q][sub [beta]] value and high spins of the decaying isomeric states, provides a favorable opportunity to search for population of known SD states in the daughter nucleus, [sup 194]Pb. Both [gamma] rays and conversion electrons were measured in singles and coincidence; however, no evidence for the population of SD states was observed. Upper limits for the population of certain SD states are presented. A possible explanation for the lack of SD band population following this [beta] decay is discussed.
