Abstract

The signature inversion in the rotational bands belonging to high-j configurations of odd-odd deformed nuclei is analysed within the framework of an axially symmetric rotor plus two-particle model. The signature inversion seen in 160Ho is reproduced very well, and the mechanism for it is pointed out. While a similar mechanism is seen to operate in 152Eu and 156Tb, it has not been possible to reproduce the inversion in these two cases.
