Emission spectra in the 2850- to 4300-¿ region produced by 0.7- to 10-keV impact of H+, H0, and He+ on CO2 and N2O have been observed. The emission consists almost exclusively of the A-X and B-X systems of CO2+ and the A-X system of N2O+. There are no emissions from excited fragments of the parent molecules. Cross sections for proton impact excitation reach maxima of 1--4¿10-16 cm2 in the collision energy range observed. Cross sections for H0 excitation reach maxima of 0.4--1¿10-16 cm2.
