Abstract Recent improvements in precision and the increase in number of molecular beam scattering experiments demand a reanalysis of the experimental data. The commonly used potential functions show a serious lack of flexibility, and fitting procedures are not unambigious. A new potential ansatz (which is a continuous modification of the (12-6)-potential) has been used to fit all available data on the alkali-rare gas systems Li-Kr, Na-Ar, Na-Kr, Na-Xe, K-Ar, and K-Kr. Aχ 2-minimum method is used as the procedure to fit the data and to estimate the errors of the parameters obtained (see Table 1). It turns out, that the shape of the potential is similar for all systems evaluated here but probably different from that derived for rare gas-rare gas systems.
