概要

• 論文の詳細を見る

• Shell structure of the single-particle spectrum for a reflection-asymmetric deformed cavity is investigated. Clear shell structure emerges for certain combinations of quadrupole and octupole deformations. Semiclassical periodic-orbit analysis indicates that simultaneous bifurcations of short periodic orbits in the equatorial plane play predominant roles in the formation of this new shell structure.
