Abstract:

The cross sections, threshold angular distribution and energy of the ionic product from the reaction CD2,Dcd were investigated as a function of projectile ion energy. The cross sections for both the ground state and the first excited state reactions of B with D2 were also measured as a function of B kinetic energy. The electronic states of H2O and H3O produced by electron bombardment of water vapour were identified. Dynamics of the reaction H2OD2,DH2DO were studied and the cross section and threshold of the reaction H2OH2,HH3 were measured. Similarly, the cross sections and the threshold of the reaction D3OD2,D2OD3 were determined. These measurements permitted an accurate determination of the proton affinity of H2, D2 and D2O. A study of the dynamic of the reaction H2OH2O,OHH3O has been initiated. A number of mechanisms are indicated but the scheme is complex and has not as yet been completely unravelled. Author
