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 he excited band depopulates at the same freqeuncy 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 [ital A][similar to]150 mass region indicates that the decay-out mechanism is strongly affected by neutron pairing correlations and the occupancy of high-[ital N] intruder orbitals.
