THEORY OF SCATTERING OF MOLECULAR BEAMS IN GASES,
Abstract
The differential cross section for molecular beams with uniform and non-uniform velocities is obtained in power series in powers of theta and pi - theta (where theta is the scattering angle in the center-of-mass system) for intermolecular potentials of the form U(r) = lambda (1/r to the nth power); and they are numerically calculated for integral n between 6 and 14. The quantum mechanical effects are neglected. The cross sections obtained are compared with the experimental results of Knauer for the scattering of a H2 beam in Hg gas and the intermolecular potential between H2 and Hg is determined to be U(r) = 273k (3.5/r) to the 7th power, (r in A, k = Boltzmann constant).
