AUTOIONIZING DOUBLE CAPTURE IN N-7+ ON HELIUM COLLISIONS AT LOW ENERGIES

We have studied the branching ratios between the single-electron capture and the double-electron capture for impact energy range. A good agreement has been found with the experiments for these ratios as well as for the differential cross-sections corresponding to the various processes which occur during the collision. The present study does not support the conclusions of another theoretical work concerning the mechanism leading to the single-electron capture. As for the populations of the substates formed by double capture, there is a fairly good agreement between both theory and experiments. © 1990 The Japan Society of Applied Physics.
