The excited states produced in collisions of N+2 and N+ with Ne have been studied by using emission spectroscopy. The emission spectra show that there are four processes of the excitation in these collision systems,namely:(1)Direct excitation of target;(2)Direct excitation of atomic projectile;(1)Direct excitation of molecular ion;(4)Charge exchange excitation. The emission cross sections for each spectral line are calculated . Acomparison of emission cross sections in collisions between N+2-Ne and N+-Ne is made. Some differences are found and the primary results have been discussed qualitatively.
