论文摘要
最低$^2p_u $，$^4p_g $和$ 2D_G $的能量是用$μ$ HARTREE准确性计算的，基于对称，明显相关的高斯叶函数。考虑有限的核质量和标量相对论校正。这项研究导致了迄今为止尚未衡量的硼龙和四重奏状态之间能量差异的问题。发现在原子光谱数据库中建议的$^2p_u \ rightArrow^4p_g $激发能量似乎被超过300〜cm $^{ - 1} $所低估。
The energies of the lowest $^2P_u$, $^4P_g$ and $2D_g$ states of the boron atom are calculated with $μ$hartree accuracy, in the basis of symmetrized, explicitly correlated Gaussian lobe functions. Finite nuclear mass and scalar relativistic corrections are taken into account. This study contributes to the problem of the energy differences between doublet and quartet states of boron, which have not been measured to date. It is found that the $^2P_u\rightarrow^4P_g$ excitation energy, recommended in the Atomic Spectra Database, appears underestimated by more than 300~cm$^{-1}$.
