Energy and Hyperfine Structure Studies of Excited State for Beryllium
-
摘要: 采用多组态相互作用方法及Rayleigh Ritz变分法 ,并考虑相对论修正、质量极化效应等 ,获得了铍原子低激发态 1s2 2s2p3 Po和 1s2 2p2 3 P高精度的相对论能量 .同时还计算了铍原子超精细结构常数 ,与其他理论和实验结果符合得很好. The Rayleigh-Ritz variational method is used with a multiconfiguration-interaction function and restricted variation method to obtain the relativistic energies of 1s 22s2p 3P o and 1s 22p 2 3Pin beryllium, including the mass polarization and relativistic corrections. Hyperfine structure is also studied to compared with theoretical and experiment data in the literature.
