Dipole rotational band in137Nd

Abstract

A dipole band with regular energy spacings has been identified in the nucleus137Nd built on aI=33/2 state atE x =5.60 MeV. The Doppler shift attenuation method analysis of a backed-target experiment allowed to extract the lifetimes of the band levels, which are of the order of 1 W. u., The resulting large B(M1) values, together with the high aligned angular momentum suggest a five-quasiparticle configuration (involving twoh 11/2 protons and twoh 11/2 neutrons).
