类铍离子N^(3+)激发态的能量、振子强度和跃迁几率(英文)

Energies, oscillator strengths and transition rates of the excited states for beryllium-like N^(3+)

利用多组态相互作用方法及Rayleigh Ritz变分法 ,计算了类铍N3 + 基态 (1s2 2s2 1S)和三个激发态(1s2 2s2 p1P0 ,1s2 2s2 p3 P0 ,1s2 2 p2 3 P)的能量 ,运用截断变分方法得到能量的改进量 ,包括了相对论能量和质量极化效应。计算了相关态的振子强度和辐射跃迁率。

The bound state (1s 22s 2 1S ) and three excited states ( 1s 22s2p 1P 0, 1s 22s2p 3P 0, 1s 22p 2 3P) of beryllium like N 3+ are calculated using the Rayleigh Ritz variational method with a multiconfiguration interaction wave function. A restricted variational method is used to extrapolate a better nonrelativistic energy. The relativistic corrections and mass polarization are included. The oscillator strengths and radiation transition rates are also calculated. Our results are in good agreement with other theoretical and experimental data.
