New measurements of the differential collision cross section for Kr + Kr are presented and, together with previously published data, are analyzed in terms of a Morse—Spline—van der Waals interatomic potential function. By means of a least-squares fitting procedure a potential is obtained which best describes the measurements. This potential also predicts second virial coefficients and vibrational-level spacings that agree well with experiment. Some of the difficulties that arise in attempting the inversion of scattering data in this and similar systems are discussed. Finally, we present a comparison with some low-temperature solid-state data.
