Chiral bands in odd-odd nuclei with rigid or soft cores

Properties of chiral bands in an odd-odd nucleus, which is treated as a system of an even-even core and a pair of particles in the pi h(11/2) circle times nu h(11/2)(-1) configuration, are calculated in the frame of the Core-Particle-Hole Coupling (CPHC) model with either a rigid triaxial or a soft core. The results of calculations for the two different cores are compared. The properties of the nucleus with the rigid, maximally triaxial (gamma = 30 degrees) and with the entirely soft core are qualitatively very similar.
