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.
