[en] Superdeformed (SD) bands in ¹⁵²Dy, ¹⁵¹Dy and ¹⁵¹Tb have been populated via the 5n, 6n and 5np evaporation channels, respectively, with the ³³S+¹²⁴Sn reaction at 160 and 170 MeV bombarding energies. Population intensities are in good agreement with existing data for SD bands in ^151,152Dy and SD yrast band in ¹⁵¹Tb. The excited 'twin' SD band in ¹⁵¹Tb with the same γ-transitions as the band in ¹⁵²Dy is populated about 5 times more strongly than by the 6n evaporation channel. This might be explained in terms of competition between proton and γ emission out of an intermediate, excited superdeformed configuration of ¹⁵²Dy. (orig.)
