Periodic-Orbit Bifurcation and Shell Structure at Exotic Deformation
K. Arita, A. Sugita, K. Matsuyanagi
Abstract
By means of periodic orbit theory and deformed cavity model, we have investigated semiclassical origin of superdeformed shell structure and also of reflection-asymmetric deformed shapes. Systematic analysis of quantum-classical correspondence reveals that bifurcation of equatorial orbits into three-dimensional ones play predominant role in the formation of these shell structures.
