NH2 profiles were measured in a discharge flow reactor at ambient temperature by monitoring reactants and products with an electron impact massspectrometer. At the low pressures used (0.7 and 1.0 mbar) the gas-phase self-reaction is dominated by a 'bimolecular' H2-eliminating exit channel with a rate coefficient of k(3b)(300 K)=(1.3+/-0.5)E-12 cm**3 molecule**-1 s**-1 and leading to N2H2+H2 or NNH2+H2. Although the wall loss for NH2 radicals is relatively small (k(w)apprxeq.6-14 s**-1), the contribution to the overall NH2 decay is important due to the relatively slow gas-phase reaction. The heterogeneous reaction yields N2H4 molecules.
