    Abstract

    A simple macroscopic model based on two-fluid liquid drop ideas is proposed for studying rotational band structure in heavy deformed doubly even nuclei. The pairing and centrifugal degrees of freedom are taken into account in a harmonic approximation. The model is then applied to study the interplay of Coriolis, centrifugal and pairing forces in some well-known backbenders and non-backbenders and it is concluded that the observed anomalies at high spins could be the result of such an interplay. Calculations for the actinides 232Th and 240Pu are also presented.
