摘要
以对角和不变法则为基础,导出了铍原子(含类铍离子)低激发态(电子组态1S22S2P、1S22P2)非相对论性能量的解析表达式;利用变分法计算了能量值,计算结果与实验值的误差小于1%.
Based on the diagonal sum rule, the energy levels of the lowly-excited states, corresponding to the 1S22S2p and 1S22P2 configurations of the beryllium-like atoms have been first derived analytically, and then calculated by variational method. The exchange interaction between the inner shell and outer shell electrons and the different screening effect of these electrons are considered. The difference between the calculated result and the experimental data is less than 1%.
