Results are reported from a calculation of the effective probabilities of electron--vibrational--rotational transitions when the state N/sup +//sub 2/B/sup 2/ ..sigma../sup +//sub u/(v' = 0) is excited by secondary electrons produced by ionization of nitrogen by a 10 keV primary electron beam. Use is made of the fact that the relative contribution from secondary electrons to emission from the first negative system of N/sup +//sub 2/ increases with distance from the center of the primary beam. The adiabatic approximation is used to calculate the transition probabilities from experimental data. It is shown that for secondary electrons, the probabilities of transitions with ..delta..k = 3, 4, 5,... are comparable in magnitude to the probabilities of transitions with ..delta..k = +- 1.
