Glory Scattering of Lithium by a Series of Molecules. I. Diatomics

The velocity dependence of the total cross section has been measured for the scattering of lithium-7 by D2, N2, O2, CO, NO, HF, HCl, DCl, HBr, HI, ICl, Cl2, and Br2. Glory undulations are observed for all systems except Cl2 and Br2 although in some cases these undulations are considerably smaller than might be expected for comparable atom–atom scattering. Potential parameters are derived for these systems. Chemical reaction, time-dependent anisotropic potentials, and inelastic processes are discussed as possible mechanisms for the observed quenching.
