Shell structure of the single-particle spectrum for reflection-asymmetricdeformed cavity is investigated. Remarkable shell structure emerges for certaincombinations of quadrupole and octupole deformations. Semiclassicalperiodic-orbit analysis indicates that bifurcation of equatorial orbits playsan important role in the formation of this new shell structure.Comment: 5 pages, latex including 5 postscript figures, submitted to Physics Letters
