摘要：

We systematically calculate the spontaneous fission half-lives for heavy and spuerheavy nuclei between U and Z=114. The spontaneous fission process is treated as a semi empirical WKB framework. The potential barrier is obtained by a generalized liquid drop model(GLDM), taking into account the nuclear proximity, the mass asymmetry, the accurate nuclear radius, and the microscopic shell correction. Macroscopic inertial-mass functions has been employed for the calculation of the fission half-lives. The results reproduce experimental data rather well.
