Luminescence for charge exchange of atom--ions with N/sub 2/ and CO molecules in the energy range 2 to 100 eV. [Cross sections]

Technical Report ·
OSTI ID:5168112
Electronically excited states of the isoelectronic molecules N/sub 2/ and CO are formed by charge exchange with several projectile ions. The vibrational occupation and excitation cross sections of these states were determined from the emission spectra. The occupations deviated strongly from the Franck-Condon distribution in the energy range investigated (2 to 1000 eV). Generally, a similar velocity dependence is found for all projectile ions (He/sup +/, Ne/sup +/, Ar/sup +/, C/sup +/, N/sup +/, O/sup +/, H/sup +/, H2/sup +/, H3/sup +/) above 50 eV. Measurement of the excitation cross sections showed a correlation with the deviation from the Franck-Condon distribution. This was more evident for smaller cross sections.
