Abstract:
The negative-parity bands with different values of K in Th-220 are analysed within the dinuclear system model which was previously used for describing the ground-state alternating-parity bands with K = 0 in deformed actinides. The model is based on the assumption that the cluster type shapes are produced by the collective motion in the mass-asymmetry coordinate. To describe the reflection-asymmetric collective modes characterized by the nonzero values of K, the intrinsic excitations of clusters are taken into account. The observed excitation spectrum, angular-momentum dependence of the parity splitting and the staggering behaviour of the B(E1)/B(E2) ratios are explained.
