Chaos in the Nucleus: SD Decay-out and Masses

Summary, in English

Some consequences of chaos in the nucleus are discussed. The decay-out from superdeformed band occurs in a region where normal-deformed states may be chaotic, and it is shown how the distribution of decay-out matrix elements may reveal the degree of chaos. The decay-out is mediated by doorway states that are not resolved in the A=190 region, but experimentally seen in 59Cu. A model for the decay-out in the A=60 region is set up and applied to 59Cu. It is discussed how errors in nuclear mass formula may be related to chaotic motion, and a theoretical model is set up and applied to chaotic masses.
