Description

sup(198,200)Po have been studied by in beam γ-spectroscopy with the sup(182,184)W(20Ne,4n) reaction at 105 to 112 MeV. Both nuclei exhibit 8+, 11-, and 12+ isomers for which lifetimes and g-factors have been measured, that determine their single particle structure. The a priori highly hindered (πhsub(9/2)isub(13/2)11-->πh2sub(9/2)8+) E3-transition becomes with 25 Weisskopf units very strong in 198Po suggesting that octupole vibrations or deformations are important in this region of nuclei.
