软件简介: brief introduction

通过考虑镜像核约束，对原子核质量公式进行了进一步改进。新的质量公式对2149个核质量的rms偏差减小到0.441MeV, 1988个核的单中子分离能的rms偏差减小到0.332MeV, 46个超重核的alpha衰变能的rms偏差减小到0.263MeV；同时能较好地再现幻数核的壳能隙（shell gaps）。计算出来的超重核的壳修正与最新的宏观微观方法得到的超重核裂变位垒比较一致。 考虑超重核的壳修正，超重岛的中心位置可能位于Z=116~120，N=176~178附近。Fortran源程序下载地址：http://www.imqmd.com/Soft/ShowInfo.asp?InfoID=16

The macroscopic-microscopic mass formula is further improved by considering mirror nuclei constraint. The rms deviation with respect to 2149 measured nuclear masses is reduced to 0.441 MeV. The shell corrections, the deformations of nuclei, the neutron and proton drip lines, and the shell gaps are also investigated to test the model. The rms deviation of alpha-decay energies of 46 super-heavy nuclei is reduced to 0.263 MeV. The predicted central position of the super-heavy island could locate at N=176~178 and Z=116-120, considering the shell corrections of nuclei. The Fortran code of the proposed model is available at http://www.imqmd.com/Soft/ShowInfo.asp?InfoID=16
