Low Energy Inelastic Atomic and Molecular Collisions.

Abstract

Ar(++) + Ar collisions are studied with particular emphasis on the single electron capture channels. The dominant process is found to result in Ar(+)(2P) + Ar(+)(3s23p4nl). A weaker process, attributed to the presence of a highly excited Ar(++) state is also seen in the angular range investigated. Our Work on D(+) + H2 showed that rotational excitation of the H2 electronic ground state is the important quasi-elastic process in the E theta 2<1.5 keV deg sq region investigated. Electronic excitation of H2 is seen to occur over a small E theta range. In addition ion-molecule work resulted in a model which could explain previous He(+) + H2 charge-exchange results. Reliable grazing-incidence soft x-ray spectra were taken for the first time showing multiplet and charge-state structure in the 60-100A range from collisions of intense 80-150 keV P(+) and S(+) ion beams with an Ar gas target.
