Periodic-Orbit Bifurcation and Shell Structure in Reflection-Asymmetric Deformed Cavity
A. Sugita, K. Arita, K. Matsuyanagi
Abstract
Shell structure of the single-particle spectrum for reflection-asymmetric deformed cavity is investigated. Remarkable shell structure emerges for certain combinations of quadrupole and octupole deformations. Semiclassical periodic-orbit analysis indicates that bifurcation of equatorial orbits plays an important role in the formation of this new shell structure.
