Plasmas created by electron beams in N2 and He-N2 and Ne-N2 mixtures at high pressures are studied experimentally. It is shown that N2 + ions in the B2 ∑u + state are produced during charge exchange of Ne2 + ions with N2 molecules. A comparison of the intensity of light from the B2∑u + → X2∑g + transition of the N2 + ion in He-N2 and Ne-N2 mixtures shows that under these experimental conditions charge exchange of Net ions with N2 is less effective than the analogous process involving He2 + ions. It is found that in an Ne-N2 mixture the intensity of emission on transitions of the 2t system of nitrogen is greater than in N2.
