Abstract
Relative intensities of the yrast and the first excited superdeformed bands in {sup 151}Tb have been accurately measured, with the EUROGAM spectrometer. It is shown that the excited band depopulates at the same frequency and spin as its identical band in the isotone {sup 152}Dy whereas the yrast band deexcites at higher rotational frequency and spin even though it is much lower in excitation energy. A classification of superdeformed bands in the A {approx} 150 mass region indicates that the decay-out mechanism is strongly affected by neutron pairing correlations and the occupancy of high-N intruder orbitals.
