Transition strengths in odd-odd Rb-80 - art. no. 044316

Lifetimes of levels in Rb-80 have been measured using the Doppler shift att enuation method. The high-spin states have been populated through the Mn-55 (Si-28,2pn) reaction at 90 MeV. Collective enhancement was observed in the B(E2) values of the two most strongly populated bands, while the B(M1) valu es of the yrast band exhibit a large alternating pattern. Transition quadru pole moments were deduced from E2 transition strengths and compared with th ose predicted by Woods-Saxon cranking calculations.
