The properties of rotational and quasirotational negative parity
bands with different values of $K$ in actinides are investigated
in the frame of dinuclear system model [1]. The model is based on
the assumption that the cluster type shapes are produced by the
collective motion in mass--asymmetry coordinate. To describe the
reflection--asymmetric collective modes characterized by the
nonzero values of $K$, the relative angular motion together with
the intrinsic excitations of the clusters are taken into account
[2]. The observed excitation spectrum, angular momentum dependence
of the parity splitting and the staggering behaviour of the
$B(E1)/B(E2)$ ratios are explained in different even-even isotopes
of Ra, Th, U and Pu.
