Studies in hot atom and radiation chemistry. Progress report, December 1, 1978-November 30, 1979. [Cl/sup +/(CO,O) CCl/sup +/; B/sup +/ + D/sub 2/; Br + ethane; charge of /sup 13/N from /sup 12/C(d,n)]
The cross section for the reaction Cl/sup +/(CO,O)CCl/sup +/ was measured over an energy range from threshold to 18 eV in the center of mass system using a tandem mass spectrometer. The threshold value yielded a heat of formation of CCl/sup +/ of 15.7 +- 0.1 eV. The angular and energy distribution of the ionic products from the reaction B/sup +/(/sup 3/P/sub u/) + D/sub 2/ was also studied at 1 to 40 eV. The product states as determined from the limiting values of the translation exergicity were BD/sup +/(/sup 2/..sigma../sup +/) and BD/sup +/(/sup 2/..pi..). Velocity contour maps indicated that the former product was probably arising through complex formation whereas the latter was proceeding by a direct mechanism. Work on the reaction Br/sup +/(D/sub 2/,D)BrD/sup +/ was initiated; both the ground state /sup 3/P and the first excited electronic state (/sup 1/D) reactions are being measured. Work was also initiated on the Br-ethane hot atom system. Inelastic and superelastic collisions between rare gas atoms and halogen ions are being investigated. The charge distribution of /sup 13/N produced by the reaction /sup 12/C(d,n)/sup 13/N over a deuteron energy range of 2.5 MeV to 14 MeV has been measured.
