Absolute total elastic cross sections for collisions of oxygen atoms with the rare gases at thermal energies

Abstract

Absolute total elastic cross sections for collisions of ground state O atoms with He, Ne, Ar, Kr, and Xe have been measured as a function of velocity in the range 0.6–2.0 km sec−1. The data are deconvoluted in the center-of-mass system and treated in terms of model potentials for the involved interactions. For the heavier rare gases a glory structure has been observed and the possible role played by multiple potentials on such structure is discussed.
