| 英文摘要 | The macroscopic deformed potential energies for super-heavy elements Z = 110, 112, 114, 116, 118 are determined within a generalized liquid drop model (GLDM). A quasi-molecular mechanism is introduced to describe the deformation of a nucleus in the GLDM and the shell model simultaneously. The macroscopic energy of a two-center nuclear system in the GLDM includes the volume-, surface-, and Coulomb-energies, the proximity effect at each mass asymmetry, and accurate nuclear radius. The shell correction is calculated by the Strutinsky method and the microscopic single particle energies are derived from a shell model in an axially deformed Woods-Saxon potential with the quasi-molecular shape. The total potential energy of a nucleus can be calculated by the macro-microscopic method as the summation of the liquid-drop energy and the Strutinsky shell correction. The theory is applied to predict the fusion barriers of the cold reactions Ni-64 + Pb-208 --> (272)110(*), Zn-70 + Pb-208 --> (278)112(*), Ge-76 + Pb-208 --> (284)114(*), Se-82 + Pb-208 --> (290)116(*), Kr-86 + Pb-208 --> (294)118(*). It is found that the neck in the quasi-molecular shape is responsible for the deep valley of the fusion barrier. In the cold fusion path, double-hump fusion barriers could be predicted by the shell corrections and complete fusion events may occur. |
