以前的一些计算α衰变半衰期的工作采用M3Y或者DDM3Y有效相互作用计算核-核势能,而且得到了合理的结果。我们在预形成结团模型框架下,尝试运用一个新的微观核核相互作用研究超重元素α衰变的半衰期。用Dirac-Brueckner-Hartree-Fock(DBHF)方法得到的核子-核子相互作用,然后用双折叠模型(DFM)计算微观核-核势能。在我们的工作中,通过符合123个中等质量和重核(Z=54～102)的实验数据得到高斯形状因 Some previous calculations of the half-life of α-decay used the effective interaction of M3Y or DDM3Y to calculate the nuclear-nuclear potential and gave reasonable results. In the framework of the preformed clumping model, we try to use a new microscopic nuclear interaction to study the half-life of α-decay overweight elements. Nucleon-nucleus interactions were obtained using the Dirac-Brueckner-Hartree-Fock (DBHF) method, and then the microscopic nuclear-nuclear potential was calculated using a bifold model (DFM). In our work, the Gaussian shape factor was obtained by fitting 123 experimental data with medium and heavy nuclei (Z = 54 ~ 102)
