Abstract
Dissociative electron attachment (DEA) to NO2 in the 7–11 eV range is studied using velocity slice imaging technique. Two distinct channels are observed in the DEA corresponding to O– + NO(A 2Σ+) and O– + NO(C 2Π and/or D 2Σ+). While NO(A 2Σ+) is found to be formed only in very high vibrational levels, NO(C 2Π and/or D 2Σ+) is found to be formed with vibrational distribution starting from v = 0. From the angular distribution of the O– ions leading to the NO(C 2Π and/or D 2Σ+) channel, we obtain the symmetry of the negative ion resonance to be dominantly B1 with small contribution from B2.
