Based on experimental measurements of the collision energy dependence obtained for the total cross sections of elastic scattering of ions of alkali metals Li/sup +/ and K/sup +/ on atoms of inert gases Ar, Kr, and Xe, as well as of the quantum glory oscillations, first discovered for ionic-atomic collisions, the interaction potentials are determined for these particles in a wide region of internuclear distances, including repulsion, the potential minimum, and long-range polarization atttraction. A method is described for obtaining the five free parameters of the potential, assumed to have the form of a piecewise-continuous function, making it possible, regardless of the variation of the potential at large and small distances, to form the potential minimum using three quantities: the depth epsilon-c of the well, the equilibrium distance R/sub m/, and the curvature k/sub epsilon-c/.
