Rotations and Vibrations in Deformed Nuclei

A general survey of phenomenological, collective-model theories, especially those based upon the hydrodynamic model of rotations and vibrations of a deformed liquid drop, is presented. Details of models of even-even, odd-odd and odd-$A$ nuclei are given as well as a discussion of electromagnetic moments and transitions in these models. The influence the vibrating and rotating nuclear surface has on alpha and beta decay of deformed nuclei is outlined. The discussion is extended to collective model calculations of the photonuclear process from which information can be obtained on the shape of nuclei in their ground states. Comparison of theory with the results of some recent experiments is given where this has been considered useful.
