Electronic Excitation in Collisions of H and H(+) with O2.
Abstract
The 115-750 nm radiation produced in collisions of 1.5-25 keV H(+) and H with O2 has been studied in an atomic beam experiment under thin-target conditions. Both for ion and neutral impact, the first negative (1N) and second negative (2N) band systems of O2(+) are the most intense spectral features. Also observed are several emissions from excited states of O and O(+). Relative cross sections for individual bands of the O2(+)1N system, were used to show that the vibrational population formed in both H(+) and H impact is in good agreement with the predictions of a simple Franck-Condon mechanism over the 2-25 keV energy range. Total cross sections for formation of O2(+) electronic states are discussed.
