✦ Synopsis

Measurements of the distribution of rotational states in a nilrogcn molecular beam before and after dencction by collision with rare gas atoms arc interpreted in terms of the intermolcculai potential. A potential of rhc form qR,e)=46[1

is used with semiclassiml theory using the sudden approximation to fit the observations. ASQI_ is known, as well as E and the size parameter, cr. the objective is to find bZ_ l~owever, the calculated state distributions arc found to systematicalty vary from those measured, irrcspcctivc or the value of b?. This result is tcntativcly esplninrd as due to the inadequacies of the 12-6 potenthl.
