Abstract

Abstract: Based on Weizscker-Skyrme (WS4) nuclear mass formula, the predictive power of the model is investigated. The deviation between the predicted masses with the WS4 model and the experimental data in AME2016 is calculated. The latest experimental data could be well reproduced by the calculated results of the WS4 nuclear mass formula,and the rms deviation of the 58 “new” masses is 0.543 MeV. The predictions of the WS4 nuclear mass formula are in good agreement with the experimental data in the heavy nuclei and superheavy nuclei region,which provides a reliable tool for the study of the new superheavy nuclei. In addition,the radial basis function approach can be used to further improve the accuracy of the WS4 nuclear mass formula.

Key words: nuclear mass formula, predictive power, radial basis function approach, superheavy nuclei
