✦ Synopsis
Noble gas dimers existing in a nozzle beam are scattered by a noble gas atomic beam. Avoiding the infIuence of higher clusters we have measured the velocity dependence of the total scattering cross section for Arz-(Ne, Ar, Kr) and Kr2 -(Ne, Ar). To determine the ratio of the cross sections for the dimer and monomer systems, we have also measured the cross sections for the corresponding monomer systems under identical target conditions. Preliminary analysis of the results indicates that a potential equivalent to twice the monomer potential can reproduce the measured dimer cross sections reasonably well.~
