The dispersion coefficients (in au) for the ground state of alkali atoms interacting with the <em>n</em>s<em>n</em>p ¹P^<em>o</em> and ³P^<em>o</em> excited states of alkaline-earth atoms

<b>Table 3.</b> The dispersion coefficients (in au) for the ground state of alkali atoms interacting with the <em>n</em>s<em>n</em>p ¹P^<em>o</em> and ³P^<em>o</em> excited states of alkaline-earth atoms. <em>n</em> = 2, 3, 4 and 5 for Be, Mg, Ca and Sr, respectively. The notation <em>a</em>[<em>b</em>] means <em>a</em> <b>×</b> 10^<em>b</em>. Dispersion coefficients which could be influenced by an accidental degeneracy with pseudo-states in the alkali atom continuum are indicated by underlining. <strong>Abstract</strong> Dispersion coefficients between the alkali metal atoms (Li–Rb) and alkaline-earth metal atoms (Be–Sr) are evaluated using matrix elements computed from frozen core configuration interaction calculations. Besides dispersion coefficients with both atoms in their respective ground states, dispersion coefficients are also given for the case where one atom is in its ground state and the other atom is in a low-lying excited state.表3 碱金属原子基态与碱土金属原子的n s n p ¹P°及³P°激发态相互作用的色散系数（单位：原子单位（atomic unit，au））。其中对于Be、Mg、Ca和Sr，n分别取2、3、4、5。记号a[b]表示a × 10^b。受碱金属原子连续谱中赝态与偶然简并影响的色散系数将以下划线标注。 摘要：本研究基于冻结核组态相互作用计算得到的矩阵元，对碱金属原子（Li至Rb）与碱土金属原子（Be至Sr）之间的色散系数进行了计算。除两原子均处于各自基态的色散系数外，本研究还给出了其中一个原子处于基态、另一个原子处于低激发态的色散系数。
