论文摘要
我们表明，Hartree-Fock-Bogoliubov（HFB）方法能够通过在用于计算核平均场的标准过程中包含一个残留的核子核子表面高斯（SGI）来描述α衰变宽度的实验值。我们称此方法为群集HFB（CHFB）方法。通过这种方式，我们纠正了由标准平均场产生的相应单粒子（SP）波函数的渐近行为。校正后的平均场成为标准平均木材撒克逊式场和与SGI相同半径的簇高斯组件之间的总和。因此，我们给出了平均场和群集电位结构的确认，这是我们以前关于α-末期宽度的工作中假定的。系统计算证明了SGI强度和分裂潜力之间的线性相关性，从而可以对超高发射器的半寿命进行可靠的预测。
We show that the Hartree-Fock-Bogoliubov (HFB) method is able to describe experimental values of alpha decay widths by including a residual nucleon-nucleon Surface Gaussian Interaction (SGI) within the standard procedure used to calculate the nuclear mean field. We call this method the Cluster HFB (CHFB) approach. In this way we correct the deficient asymptotic behaviour of the corresponding single-particle (sp) wave functions generated by the standard mean field. The corrected mean field becomes a sum between the standard mean Woods-Saxon-like field and a cluster Gaussian component centered at the same radius as the SGI. Thus, we give a confirmation of the mean field plus cluster potential structure, which was assumed in our previous work on alpha-decay widths. Systematic calculations evidence the linear correlation between the SGI strength and fragmentation potential, allowing for reliable predictions concerning the half lives of superheavy emitters.
