N is detailed. The method creates a set of cross-sections from parameterized shapes available from literature, Born approximations, and cubic splines. The most fit cross-sections generated in this way are those which, when input to a multi-term Boltzmann equation solver, best reproduce experimental drift velocity data. The cross-sections generated in this way are compared with cross-sections calculated using the R-matrix method software Quantemol-EC.
