Title: Selective studies of the excited rotational bands in the superdeformed nucleus {sup 151}Tb

Abstract

The experimental study of the unresolved rotational bands, forming ridge structures in {gamma}-{gamma} spectra, has been performed on the superdeformed nucleus {sup 151}Tb. {gamma} transitions from the reaction {sup 27}Al, at 155 MeV, on {sup 130}Te were measured with EUROBALL IV in high fold coincidence. The analysis of the intensities and count fluctuations of the ridge structures shows the existence of {approx_equal}30 discrete rotational bands of superdeformed nature, half of which is in direct coincidence with the superdeformed yrast band. A comparison with band mixing model predictions and with a previous work on the superdeformed nucleus {sup 143}Eu is presented.
