类铍离子N3+激发态的能量、振子强度和跃迁几率

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.%The bound state (1s22s21S) and three excited states (1s22s2p1P0, 1s22s2p3P0, 1s22p23P) o f beryllium-like N3+ are calculated using the Rayleigh-Ritz variational method with a multiconfiguration interaction wave function. A restricted variati onal method is used to extrapolate a better nonrelativistic energy. The relativi stic corrections and mass polarization are included. The oscillator strengths an d radiation transition rates are also calculated. Our results are in good agreem ent with other theoretical and experimental data.
