概要

• 論文の詳細を見る

• We show that the closed-shell configurations in the axially-symmetric harmonic-oscillator potential with the frequency ratio ω_⊥/ω_z=2 are unstable against octupole deformation when their upper-most shell quantum numbers N^F_<Sh> are even, whereas they are stable when N^F_<Sh> 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.
