    "abstract": "Correspondence between classical periodic orbits and quantum shell structure\nis investigated for a reflection-asymmetric deformed oscillator model as a\nfunction of quadrupole and octupole deformation parameters. Periodic orbit\ntheory reveals several aspects of quantum level structure for this\nnon-integrable system. Good classical- quantum correspondence is obtained in\nthe Fourier transform of the quantum level density, and importance of periodic\norbit bifurcation is demonstrated. Systematic survey of the local minima of\nshell energies in the two-dimensional deformation parameter space shows that\nprominent shell structures do emerge at finite values of the octupole\nparameter. Correspondences between the regions exhibiting strong shell effects\nand the classical bifurcation lines are investigated, and significance of these\nbifurcations is indicated.",
