Particle Interchange Reactions Involving Plasma Impurity Ions and H2, D2, and HD

Abstract

A review with 63 refs. is presented. Particle interchange reactions are discussed, in which the ion is a plasma impurity with a charge state q = 1 and the mol. is H2, D2 or HD. The work was performed on a guided-ion-beam tandem mass spectrometer. Many endothermic particle interchange reactions between metallic ions and H2(D2) follow a pattern: the cross section rises from an apparent threshold, peaks at an energy close to the dissocn. energy of the neutral reactant, and then decreases relatively rapidly.
