The behavior of an atom-rigid rotor scattering system is investigated for the case when much energy is in internal states and only a little is in translational motion. The l-average coupled and recoupled states approximations are shown to fail completely for inelastic collisions in this regime. These approximations are also shown to be very inaccurate for transitions between highly excited states and slightly excited states and vice versa. L-labeled coupled states cross sections for a transition are proven to be directly proportional to those for the reverse transition, a symmetry not shown by exact cross sections.

    Abstract. We present an analysis of new data from Experiment E850 at BNL. We have characterized the inclusive cross section near the endpoint for pp cxclusive scattering in Hydrogen and in Carbon with incident beam energy of 6 GeV. We select events with a pair of back-to-back hadrons at large...

    A new computational approach has been used to evaluate the rotationally summed, vibronically elastic integral cross sections from the scattering of slow electrons (energy ranging from 1.0 eV up to 40.0 eV) by tetrafluoromethane molecules in the gas phase. The various symmetry components have...

    A method to deconvolute experimental differential cross sections is presented. The procedure removes the effect of the angular divergence of the primary beam, the finite size of the detector, and multiple scattering. The resulting cross section is the optimal experimental result. The method also...
