Low Energy Atomic Collisions.

Abstract

Measurements were made using either crossed or merging molecular beams. For the chemi-ionization reactions the relative energy of the reactants was varied from 0.01 to 10 eV, whereas for some of the ion-molecule processes energies of several hundred electron volts were used. The reactants included ground-state and metastable He, Ne, and Ar and H, D, N+, O+, Na, Kr, CO, NO, H2+, D2+, and HeD+. Measurements of absolute and relative cross sections as well as energy distributions of product ions were obtained. Unique techniques that were developed for studying the above reactions are described. In addition, general observations are made of the dynamics, cross sections, branching ratios, etc., for these processes. The studies were made to gain a better understanding of the dynamics of low energy atomic collisions and to attempt to define the role played by the kinetic and internal energy of reactants. Another goal of the program was to provide data to assist in the formulation of theory.
