Differential measurements on elastic and rotationally inelastic Ne*( 3P0,2)-H2 collisions at thermal energies

Abstract
A velocity selected crossed beam experiment, using a double chopping technique, is described. Its resolution is good enough to discriminate rotationally inelastic Ne*(2p53s, 3P0,2) on H2 collisions from purely elastic ones. Elastic (0 → 0) and inelastic (0 → 2) differential cross sections in the C.M. frame are given, for a relative energy of 67 meV
