Abstract

Lifetimes of states in four of the M1 bands in Pb-198,Pb-199 have been determined through a Doppler-shift attenuation method measurement performed using the GAMMASPHERE array. The deduced B(M1) values, which are a sensitive probe of the underlying mechanism for generating these sequences, show remarkable agreement with tilted axis cranking (TAG) calculations. The results represent clear evidence for a new concept in nuclear excitations: ''magnetic rotation.''
