Dissociative recombination cross sections for NH/sub 4//sup ts+/ ions and electrons

Journal Article · · Phys. Rev., A; (United States)
Cross sections for electron-NH/sub 4//sup ts+/ recombination have been measured for an electron energy range of 0.065 < or = E < or = 2.00 eV using a trapped-ion technique with an ion temperature of approx. 340 K. The cross section sigma deduced from these measurements can be represented by 4.30 x 10/sup -/16E/sup -1.40/ for 0.050 < or = E < or = 0.3 eV and by 3.73 x 10/sup -/17E/sup -3.43/ for E > 0.3 eV. There is a total uncertainty in the measurements of +- 60%. Using a Maxwellian electron-velocity distribution, recombination-rate coefficients were calculated and compared with measurements of Huang, Biondi, and Johnsen.
