Abstract
The long-range coefficients Cn (n=6, 8, 10) have been calculated for the molecular states corresponding to the interactions Na(3s)+K(4s) and Na(3s)+K(4p) using a perturbative model the authors recently proposed. For the ground state they obtained the following results (in au) C6=-2803, C8=-201516, C10=-17674349 in good agreement with the values deduced from an accurate RKR potential curve just determined.
