Abstract

Translational energy spectra have been measured on N2+ product ions resulting from 2-keV charge-stripping collisions between N+ions and He. The projectile N+ ion beam is produced under varying ion source conditions so as to contain different fractions of a long-lived metastable component. By measuring the endoergic energy defect for charge stripping from ground-state and excited-state projectiles at different electron energies in the ion source, the quantal identity of the N+ metastable state is deduced to be either 2s2p22p' 1D° , which lies 17.9 eV above the 2s22p2 3P ground electronic state, or 2s22p3s 1P°, whose excitation energy is 18.5 eV.
