The properties of the states of the alternating parity bands in actinides and Ba, Ce, and Nd isotopes are analyzed within a cluster model. The model is based on the assumption that cluster-type shapes are produced by the collective motion of the nuclear system in the mass asymmetry coordinate. The calculated spin dependences of the parity splitting and of the electric multipole transition moments are in agreement with the experimental data.
