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 Ur lambda 1r 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 Ur 273k 3.5r to the 7th power, r in A, k Boltzmann constant.
