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 O(+)+N2 yields NO(+)+N 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. (Author)
