Potential energy surfaces for superheavy elements

A specialized two-center shell model has been developed accounting for the splitting of a deformed parent nucleus into two ellipsoidal deformed fragments. The potential is based on two deformed oscillator wells in direct correspondence with the shape change of the nuclear system. Spin-orbit and squared angular momentum operators are calculated also as shape dependent. The Strutinsky method yields the shell corrections for different mass asymmetries. The macroscopic part of the total deformation energy is calculated using the Yukawa-plus-exponential model. Potential energy surfaces are presented for superheavy elements (114,284), (118,292) and (120,304). (author)
