Borkenhagen, U

A scattering experiment is described in which absolute inelastic collision cross sections were measured for transitions between defined (J,M) rotation states of CsF in collisions with atoms and molecules. The improved resolving power of the equipment allowed a relatively accurate measurement even of the very small inelastic rotation cross sections for collisions with rare gas atoms. The nearly full polarization of the CsF beam allowed observation of the ..delta..M transitions of the CsF molecule. The target was a nozzle jet, in order to take advantage of the polarization of the CsF beam. An extensive Monte Carlo simulation of the experiment was carried out in order to account for the resolution of the equipment. Differential cross sections were calculated for the relevant transitions by using a simple model.
