摘要: The nucleus /sup 152/Dy, with sharp ridges in the ..gamma..-..gamma.. energy correlation matrix, stands out from three neighboring nuclei which exhibit less pronounced structures. include observed discrete superdeformed band, but must be composed mainly of unresolved bands, decay predominantly to deformed states. A simple model is proposed.
