Nuclei at High Angular Velocities

Part of the NATO ASI Series book series (NSSB, volume 139)

Abstract

High spiry states in nuclei have been investigated intensively during the last years. A number of interesting phenomena have been observed, others are predicted. The theoretical description of these phenomena requires in principle the solution of a quantum mechanical many body problem with a large, but finite number of particles. Various approximations are necessary. The mean field approximation connected with broken symmetries plays the central role. It predicts deformations and superfluid behavior in many nuclear ground states. With increasing spin and increasing excitation energy various shape changes and phase transitions can occur. In addition one finds single particle excitations and level crossing phenomena. The semiclassical Cranking approximation provides in principle a tool to describe all these phenomena in a selfeonsistent and unified way. There are, however, a number of points, where it clearly fails. Fluctuations have to be taken into account and a full quantum mechanical treatment seems to be necessary. New methods, which take into account those points are discussed.
