Abstract

198,200Po have been studied by in beam γ-spectroscopy with the182,184W(20Ne,4n) reaction at 105 to 112 MeV. Both nuclei exhibit 8+, 11−, and 12+ isomers for which lifetimes andg-factors have been measured, that determine their single particle structure. The a priori highly hindered (πh 9/2 i 13/211−→πh 2/29 8+)E3-transition becomes with 25 Weisskopf units very strong in198Po suggesting that octupole vibrations or deformations are important in this region of nuclei.
