## The dispersion coefficients (in au) for the ground state of alkali atoms interacting with the *n*s*n*p ^{1}P^{o} and ^{3}P^{o} excited states of alkaline-earth atoms

#### dataset

Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.

**Table 3.** The dispersion coefficients (in au) for the ground state of alkali atoms interacting with the *n*s*n*p ^{1}P^{o} and ^{3}P^{o} excited states of alkaline-earth atoms. *n* = 2, 3, 4 and 5 for Be, Mg, Ca and Sr, respectively. The notation *a*[*b*] means *a* **×** 10^{b}. Dispersion coefficients which could be influenced by an accidental degeneracy with pseudo-states in the alkali atom continuum are indicated by underlining.

**Abstract**

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.
