PHOTONS SHEDDING LIGHT UPON CHARGE-EXCHANGE PROCESSES IN COLLISIONS OF 24 KEV O-3+ WITH ATOMIC-HYDROGEN

The state selective electron capture cross sections for 24 keV O3+ colliding on atomic hydrogen, obtained by photon emission spectroscopy show that the 3s 3P0 is the dominant capture channel, which is in contradiction with recent fully quantal calculations. Our measurements are qualitatively in agreement with recent translational energy spectroscopy measurements, although the absolute values of the cross sections are found to be larger. However the sum of all our state selective electron capture cross sections is in agreement with total one electron capture measurement
