Abstract

The emission spectrum of the Meinel band system (A  2Πu –X2Σ+g ) of N+2 was obtained in the region between 0.72 and 1.6 μm by electron impact excitation of N2. The relative excitation function is presented for the (0, 0) band from 22 to 120 eV. Cross sections of the Meinel bands that fall in this region were measured relative to the (2, 0) Meinel band. The results obtained are in good agreement with previously published values below 1.1 μm except for the (0, 0) band which is 30% higher. The electronic transition moment at large internuclear distances is found to agree with theoretical estimates.
