Abstract:

This report covers studies of ion molecule reactions done with mass selection of the primary ion beam. There are five separate sections 1 The cross section for the important reaction ON2 yields NON has been measured from about 0.5 e.v. to 35 e.v. It has a broad maximum of 4 x 10 to the 16th power sq cm at 13 e.v. and, very surprisingly, drops off rapidly above this energy and, more slowly below this energy. 2 Isotope effects in reactions of HD ions with HD molecules and rare gas atoms have been studied. 3 Some theoretical speculations on the importance of quantum-mechanical resonance forces in ion-molecule reactions are given. 4 Cross sections for dissociative ionization of N2 and N2O by rare gas ion impact have been measured. 5 Reactions, including dissociative ionization, of rare gas ions with N2O, C2H4, and D2 have been studied.
