Dissociative Recombination Study of Na(+) (D2O) in a Storage Ring
Abstract
The dissociative recombination of Na(+) (D2O) ion has been studied at the heavy-ion storage ring CRYRING (Manne Siegbahn Laboratory, Stockholm University). The cross section has been measured as a function of center-of-mass energy ranging from 1 meV to 0.1 eV and found to have an E (sup -1.37) dependence. The rate coefficient has been deduced to be (2.3 +/- 0.32) X 10(exp -7) x T(sub e/300)(exp -0.95 +/- 0.01)cu cm s(exp -1) for T(sub e) = 50-1000 K. The branching ratios have been measured at 0 eV. Of the four energetically accessible dissociation channels, three channels are found to occur although the channel that breaks the weak Na(+) -D2O bond is by far dominant.
