    By taking into account the surface diffuseness correction for unstable nuclei, the accuracy of the macroscopic–microscopic mass formula is further improved. The rms deviation with respect to essentially all the available mass data falls to 298keV, crossing the 0.3MeV accuracy threshold for the first time within the mean-field framework. Considering the surface effect of the symmetry potential which plays an important role in the evolution of the “neutron skin” toward the “neutron halo” of nuclei approaching the neutron drip line, weobtain an optimal value of the symmetry energy coefficient J=30.16MeV. With an accuracy of 258keV for all the available neutron separation energies and of 237keV for the α-decay Q-values of super-heavy nuclei, the proposed mass formula is particularly important not only for the reliable description of the rprocess of nucleosynthesis but also for the study of the synthesis of super-heavy nuclei.
