- Abstract
- High-spin rotational structures in the odd-odd nuclei Pr-130,Pr-132 have
been studied via the Pd-104 + S-32 reaction at 160 MeV. Several states below
the previously reported negative- and positive-parity states have been
established through the observation of low-energy transitions, leading to
new spin assignments for all observed levels. The bands based on the pi
h(11/2) x nu g(7/2) and pi h(11/2) x nu h(11/2) configurations have been
extended at much higher spins. Detailed interacting boson-fermion-fermion
model calculations have been performed for the two nuclei, which reveal the
complex structure of the new observed low-lying states. The change from
inverted to normal signature at high spin and the staggering pattern of all
observed bands are well reproduced, being explained by the interplay between
a new term introduced in the boson quadrupole operator and the residual
quadrupole-quadrupole interaction. (C) 1998 Published by Elsevier Science
