类铍离子N3+激发态的能量、振子强度和跃迁几率
Energies, oscillator strengths and transition ratesof the excited states for beryllium-like N<sup>3+</sup> ion
摘要
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(1s22s21S)和三个激发态(1s22s2p1P0, 1s22s2p3 P0, 1s22p23P)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.计算结果与其它理论和实验结果符合得很好.
Abstract
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.
