    "abstract": "An oscillatory pattern in the smoothed quantum spectrum, which is unique for\nsingle-particle motions in a reflection-asymmetric superdeformed oscillator\npotential, is investigated by means of the semiclassical theory of shell\nstructure. Clear correspondence between the oscillating components of the\nsmoothed level density and the classical periodic orbits is found. It is shown\nthat an interference effect between two families of the short periodic orbits,\ncalled supershell effect, develops with increasing reflection-asymmetric\ndeformations. Possible origins of this enhancement phenomena as well as quantum\nsignatures of period-multipling bifurcations are discussed in connection with\nstabilities of the classical periodic orbits.",
