The emission spectra in collision process between He2+ and Ne, Ar have been measured using optical methods, by Optical Multichannel Analysis. System. The experimental results demonstrate that there are three channels of excitation in these collision systems: double-electron capture into excited states, single-electron capture into excited states and direct excitation of projectile and target by incident ion impact. Emission cross sections of HeI, HeII, NeI, NeII and ArI, ArII have been obtained from calculations. Some comparisons of emission cross sections between He2++ Ne and He2++Ar have been made.
