Abstract

High-spin states in ¹³¹Nd were populated in the reaction ⁹⁴Mo(⁴⁰Ca,2pn) at a beam energy of 180 MeV. Over 170 new transitions were placed in a level scheme that consists of seven rotational structures. The bands were given configuration assignments based on their B(M1)/B(E2) ratios (for the strongly 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-band mixing calculations were performed in order to interpret the low-spin interaction observed in the [411]1/2 band. An examination of the signature splitting for the [541]1/2 bands in ^129,131,133Nd revealed information regarding the parentage of the orbital as well as a signature inversion at higher spin.
