Abstract

Using a Rotational Infinite Order Sudden Approximation (RIOSA) to describe the exiting continua X+BC(v’,j’) yielded in the vibrational predissociation of X ... BC complexes, we outline a fitting procedure of the Van der Waals interaction to get agreement with the available experimental data. Assuming an additive pairwise model of Lennard-Jones or Morse atom-atom functional forms, reasonable parameters are obtained under a low computational cost for the He ... ICI(B) and Ar ... Cl2(B) systems.
