Scientific paper

In order to obtain data on the relative importance of the resonant electron impact quenching of metastable molecules in the upper atmosphere, the resonant cross sections for electron scattering by metastable nitrogen in the A3Sigma-u(+) state were calculated by means of the 'boomerang' model. Quenching rates for this state were then evaluated for 130, 170, and 210 km altitudes. In view of the less than about 0.005/sec quenching rates obtained, even with respect to the radiative transition rate, the process considered is unimportant for A3Sigma-u(+) nitrogen populations in the earth's thermosphere.
