这项工作中提出的加权振荡器强度 (gf) 和寿命是在多配置 Hartree-Fock 相对论方法中进行的。在此计算中，通过最小二乘法优化静电参数，以改进对实验能级的调整。该方法产生的 gf 值与强度观测值更加一致，寿命值更接近实验值。在这项工作中，我们修改了所有实验上已知的电偶极子 Si VII 谱线。
The weighted oscillator strengths (gf) and the lifetimes presented in this work were carried out in a multiconfiguration Hartree-Fock relativistic approach. In this calculation, the electrostatic parameters were optimized by a least-squares procedure in order to improve the adjustment to experimental energy levels. This method produces gf-values that are in better agreement with intensity observations and lifetime values that are closer to the experimental ones. In this work we revised all the experimentally known electric dipole Si VII spectrum lines.
