Inversion of Velocity-Averaged Differential-Cross-Section Data to an Intermolecular Potential

Abstract

Utilizing generating functions, a method was constructed that retrieved the intermolecular potential from non‐velocity‐selected elastic‐scattering data. These generating functions were tested and found to be a slowly varying function of the potential, thereby making them available for use in a linearized Taylor series expansion technique, coupled with a least‐squares procedure, that inverted elastic‐scattering data. The sensitivity of the averaged differential cross section to the form of the potential was noted.
