DYNAMICAL COUPLING OF ROTATION WITH THE PAIRING FIELD IN HEAVY NUCLEI

Abstract

The macroscopic–microscopic model with the Lublin–Strasbourg Drop, the Yukawa–folded single-particle potential and a monopole pairing force is used together with the cranking model to describe rotational bands in even–even actinide ( Ra – Cn ) isotopes. The pairing strength is adjusted for every nucleus to reproduce the experimentally known energy of the rotational 2+ state. The average pairing strength obtained in this way is used to predict the rotational states in superheavy No – Cn nuclei. A simple mechanism which takes into account a dynamical coupling of rotation with the pairing field is explained in detail.
