| Abstract: | The Multi-configuration Dirac-Fock method is employed to compute the fine structure energies of the 1s22s2p3P0,1 levels of Be-like ions. The present calculations are in good agreement with existing theoretical and experimental results. On the basis of this, the hyperfine interaction diagonal and off-diagonal constants of the 1s22s2p3P0,1 levels are calculated. The effects of electron correlation and Breit interaction on these properties are investigated. |
