Abstract
A dipole band with regular energy spacings has been identified in the nucleus Nd-137 built on a I=33/2 state at E(x)=5.60 MeV. The Doppler s hift attenuation method analysis of a backed-target experiment allowed to extract the lifetimes of the band levels, which are of the order o f 1 W. u.. The resulting large B(M1) values, together with the high al igned angular momentum suggest a five-quasiparticle configuration (inv olving two h(11/2) protons and two h(11/2) neutrons).
