Abstract
The extended average level version of the multiconfiguration Dirac-Fock method is used to calculate the fine-structure intervals of the 1s22s2p configuration in the beryllium isoelectronic sequence. These results are compared with experimental data, theoretical results of Cheng, Kim and Desclaux (1979), and the semi-empirical results of Edlen (1981). The present results are in excellent agreement with experimental data.Keywords
