Abstract

The odd-proton Eu141 nucleus is studied with the Cd110(35Cl,2p2n) reaction populating states in seven distinct bands. For the yrast band, high spin states are followed up to I=43/2- and a band crossing, due to the alignment of the second and third h11/2 protons, is observed at a rotational frequency Latin small letter h with strokec=0.37 MeV. For the positive-parity bands, only the three-quasiparticle configuration, namely, g7/2-[h11/2]2, is observed up to high spins. In addition, two I=1 bands with no E2 crossovers are found in this nucleus. The cause of the relatively strong M1 transition bands can be explained by a drastic shape change due to the alignment of an h11/2 neutron pair. A systematic comparison amongst the N=78 isotones, Pr137, Pm139, and Eu141, is made.
