The dissociative recombination of Na{sup +}(D{sub 2}O) 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)x10{sup -7}(T{sub e}/300){sup -0.95{+-}}{sup 0.01} cm{sup 3} s{sup -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{sup +}-D{sub 2}O bond is by far dominant.
