【摘要】 本文使用基于微扰理论的代数方法（AM）,研究了碱金属Na₂分子的X¹∑_g⁺、6¹∑_g⁺、1³Δ_g、2³Δ_g、1³∑_g^-、A¹∑_u⁺、7³Δ_g等七个电子态的离解能;然后使用最近提出的新公式计算了这些电子态的离解能,并分别与离解能的实验值进行了对比.结果表明:使用新公式得到的分子离解能与实验值更为接近.对于那些用实验方法还难以获得其离解能的电子态,该式提供了一种获得其离解能的新方法.更多还原

【Abstract】 The dissociation energies of seven electronic states X¹∑_g⁺、6¹∑_g⁺、1³Δ_g、2³Δ_g、1³∑_g^-、A¹∑_u⁺ and 7³Δ_g of alkali-metal Na₂ molecule are calculated using the algebraic method（AM） based on the perturbation theory.Then the dissociation energies of these states are calculated using the new analytical formula proposed recently.The results show that the dissociation energies gained by new analytical formula agree excellently with the experimental values.It appears that the dissociation energy of an electronic state whose experimental value is difficult to obtain can be expected using the new formula.更多还原
