Abstract

New results on the superdeformed 196^{196}Bi nucleus a re reported. We have observed with the EUROBALL IV γ\gamma-ray spectrometer array a superdeformed trans ition of 124 keV which is the lowest observed energy γ\gamma-ray in any superdeformed nucleus. We have de velopped microscopic cranked Hartree-Fock-Bogoliubov calculations using the SLy4 effective force and a realistic surface p airing which strongly support the Kπ=2K^\pi=2^-(π\pi[651]1/2ν\otimes \nu[752]5/2) assignment of this su perdeformed band
