We estimate rates for the dissociative recombination (DR) of NO2+β +
eβ. Although accurate excited state potential energy curves for the excited
states of the neutral are not available, we estimate that the 1 2{\Phi}gβ
and the 1 2{\Pi}gβ states of the neutral may intersect the ground state
cation potential energy surface near its equilibrium geometry. Using fixed
nuclei scattering calculations we estimate the rate for direct DR via these
states and find it to be significant. We also perform approximate calculations
of DR triggered by the indirect mechanism, which suggest that the indirect DR
rate for NO2+β is insignificant compared to the direct rate.Comment: Submitted to Phys Rev
