Abstract
Dispersion coefficients for the long-range interactions of the first four excited states of He, i.e., He(2 S-1,S- 3) and He(2 P-1,P- 3), with the low-lying states of the alkaline earth atoms Mg, Ca, and Sr are calculated by summing over the reduced matrix elements of multipole transition operators.
