碱金属原子振子强度的核实极化效应

Core Polarization Effect for Oscillator Strengths of Alkali Atoms

为了突出考虑碱金属原子中价电子和原子实的关联,作者在文献[2]的基础上又引入了核实偶极极化势。由此,本文对原子锂、钠及类锂原子系列共振跃迁的振子强度和跃迁能就该势引入前后作了相应的对比计算。结果表明,在振子强度的X_a过渡态计算模式下,引入核实极化效应,对于碱金属原子最主要的共振跃迁的振子强度计算有显著改进。

In order to consider specially the correlation between valence electron and core of alkali atoms, the core-dipole polarization potential has been introduced into our model for oscillator strength"spin-polarization X_α transition state calculation"(Ref.[2]). The transition energies and oscillator strengths are calculated of LiI, NaI, and like Li sequence for resonance transitions both with and without this potential. A comparison of data shows that these calculations are improved by the introduction of core polarization effect under our calculative model.
