Abstract

The collision-energy/electron-energy-resolved two-dimensional Penning ionization electron spectrum for N₂/He*(2³S) was observed in the collision-energy range 70-380 meV. A large peak shift to higher electron energies and band width broadening were observed for the A state with increase of collision energy in comparison to those for the X and B states. Branching ratios for the three ionic states of N⁺₂ as a continuous function of collision energy were investigated. The order of the branching ratios changes from B > X > A to A > B > X in the 100-200 meV collision energy region.
