Shape coexistence of superheavy nuclei

摘要：

Shape coexistence appears in the region of superheavy nuclei.Calculations for the nobelium isotopes have been carried out with the cranking TRS model.It shows that normal deformed and superdeformed prolate shapes coexist.Particularly for the nuclei 248,250No,the ground states are uperdeformed.The kinematic moments of inertia are calculated and they agree well with available experimental results.As rotational frequency increases,the Routhians of the superdeformations decrease and the superdeformed shapes will become yrast states at high spins.
