摘要：

We show that the closed-shell configurations in the axially-symmetric harmonic-oscillator potential with the frequency ratio omega(perpendicular-to)/omega(z) = 2 are unstable against octupole deformation when their uppermost shell quantum numbers N(sh)F are even, whereas they are stable when N(sh)F are odd, in agreement with the recent suggestion by Nazarewicz and Dobaczewski. We also suggest a possible relationship between the octupole instability of the superdeformed shape and the supershell effect in reflection-asymmetric superdeformed potentials.
