✦ Synopsis


The relative populations of vibrational levels in the A 2nu state of CO; were derived from measured band intensities of the CO; A 2Qr -+ X 2"g emission system excited by charge transfer collisions of 100-5000 eV Hz and He+ ions with COa. At relative laboratory velocities above 4 X 10' cm/set the vibrational energy distribution was independent of velocity, but differed from that obtained by photoelectron spectroscopy. At velocities below 4 X lo7 cm/set the relative populations of low vibrational states increased monotonically with decreasing projectile ion velocity.
