軟件簡(jiǎn)介

通過(guò)考慮鏡像核約束，對原子核質(zhì)量公式進(jìn)行了進(jìn)一步改進(jìn)。新的質(zhì)量公式對2149個(gè)核質(zhì)量的rms偏差減小到0.441MeV, 1988個(gè)核的單中子分離能的rms偏差減小到0.332MeV, 46個(gè)超重核的alpha衰變能的rms偏差減小到0.263MeV；同時(shí)能較好地再現幻數核的殼能隙（shell gaps）。計算出來(lái)的超重核的殼修正與最新的宏觀(guān)微觀(guān)方法得到的超重核裂變位壘比較一致。 考慮超重核的殼修正，超重島的中心位置可能位于Z=116~120，N=176~178附近。

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 .
