Abstract：
The mass differences of mirror nuclei have been calculated using the Skyrme-Hartree-Fock model. The deviation of these masses differences from the corresponding experimental results is a longstanding problem and has been studied intensively. In this paper we studied this anomaly systematically. The calculations show that significant changes in the evolution pattern occur around the magic numbers. After the Skyrme force parameters are adjusted to reflect this shell effect, we found that this anomaly is significantly reduced. This shows that the anomaly is dependent on shell closure.
