Abstract
Cross-sections for electronic excitation and de-excitation among the ground state and lowest-lying seven electronic excited states of carbon monoxide(CO)by low-energy electron impact are computed using the R-matrix method.The excitation cross-sections from the ground state to the electronic states a3Π,a'3E+and A1Π agree with previous experimental and theoretical results.In addition,the cross-sections for the I1E-and D1Δ states of CO,which will cascade to CO a'3E+and A1Π states,are calculated.Furthermore,in contrast to the typical increase in electronic excitation cross-sections with collision energy,the de-excitation cross-sections show a negative trend with increasing energy.
