Velocity dependences of the total collision cross sections for scattering of helium by argon, neon by krypton and neon by xenon were measured using a time of flight method of velocity selection. For neon scattering glory oscillations were observed from which values of EY, (the product of the welI de
The widely quoted semiclassical inversion of the 4He-4He total scattering cross section data in the region of the low repulsive wall is shown to be inconsistent with both a recent ab initio and a semi-empiriui potential representing the helium interatomic forces. Further low-energy scattering data i
Absolute total elastic cross scctions for Ne-Ar, Ne-Kr, and Ne-Xe solhsions have been measured in the 0.5-1.4 km 5' veiocity range. The data have been analyzed on the basis of tbe Lennard-Jones (12,6) and BuckinSham-Corner (6,8,10) potential models. For the long dΓstance ranges mainly probed by the
