摘要: 利用多组态相互作用方法及Rayleigh-Ritz变分法,计算了类铍离子Ne6+基态1s22s2 1S和激发态1s22s2p 1Po、1s22s2p 3Po、1s22p2 3P的非相对论能量,运用截断变分方法进一步饱和函数空间得到能量的改进量,并考虑相对论修正、质量极化效应等获得了高精度的能量计算值。同时还计算了跃迁辐射波长、振子强度和跃迁率。

Abstract: The Rayleigh-Ritz variational method is used with a multi-configuration-interraction wave function on the bound state 1s22s21S,and the excited states 1s22s2p1Po,1s22s2p 3Po,1s22p2 3P for the berylliumlike Ne6+. A restricted varia-tional method is used to obtain an additional nonrelativistic energy for these states. The relativistic corrections and mass polarization are taken into consideration in the calculation of total energy. The wavelengths,oscillator strengths and radiation rates are also calculated.

Key words: berylliumlike ion, excited state, oscillator strength
