Table 4. The dispersion coefficients (in au) for the ground state of alkali atoms interacting with the ns(n − 1)d ¹D^e and ³D^e excited states of calcium and strontium. The notation a[b] means a × 10^b.

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.
