Abstract

Total cross sections for collisions of Helium atoms with other rare gases have been measured by modulated molecular beam technique. The results are used to determine the interaction constants of the van der Waals potential (V(r)∼ −C/r6). For this purpose, an indirect procedure is adopted, since the well known approximation ofMassey andMohr (QC2/5) is not applicable for Helium scattering experiments at thermal energies.

The van der Waals constants obtained are in agreement with values determined from experimental data on transport properties in gases.
