摘要：

The structure of recently discovered identical superdeformed bands in Tb151 and Dy152, and in Gd150 and Tb151 are discussed in terms of the strong-coupling approach. Based on the experimental evidence that the superdeformed core of Dy152 is extremely insensitive to the polarization effects induced by the odd particle, the bands are shown to exhibit the presence of the pseudo SU(3) symmetry at extreme conditions of large elongations and high spins. © 1990 The American Physical Society.
