Abstract
High-spin states in Nd-131 were populated in the reaction Mo-94(Ca-40,2pn) at a beam energy of 180 MeV. Over 170 new transitions were placed in a leve l scheme that consists of seven rotational structures. The bands were given configuration assignments based on their B(M1)\B(E2) ratios (Eor the stron gly coupled bands), aligned angular momentum, observed band crossings, and signature splitting. Several quasiparticle alignments were observed in the bands and compared with predictions from the cranked shell model. Three-ban d mixing calculations were performed in order to interpret the low-spin int eraction observed in the [411]1/2 band. An examination of the signature spl itting for the [541]1/2 bands in (129),(131),Nd-133 revealed information re garding the parentage of the orbital as well as a signature inversion at hi gher spin.
