    "abstract": "A semiclassical analysis is made of the origin of an undulating pattern in\nthe smoothed level density for a reflection-asymmetric superdeformed oscillator\npotential. It is suggested that, when the octupole-type deformation increases,\nan interference effect between two families of periodic orbit with the ratio of\nperiods approximately 2:1 becomes stronger and thus a pronounced ``supershell\u0027\u0027\nstructure appears.",
