Long-range interaction of two metastable rare-gas atoms
A. Derevianko, A. Dalgarno
Abstract
We present semiempirical calculations of long-range van der Waals interactions for two interacting metastable rare-gas atoms Ne through Xe. Dispersion coefficients C6 are obtained for homonuclear molecular potentials asymptotically connecting to the ns(3/2)2 + ns(3/2)2 atomic states. The estimated uncertainty of the calculated C6 dispersion coefficients is 4%.
