Abstract
We have used the University of Chicago Scanning Transmission Ion Microscope to measure the yield of H+2 from beams traversing 15 Å to 40 Å carbon films. At 12.5 keV/H the measured yields were about 1 to 10%. Analysis of the yields of H+2 from this experiment and other experiments at higher energy in terms of the rms internuclear separation of the emergent particles and the dwell time in the carbon film shows that the separation is the more important factor. Graphs of yields vs. internuclear separation provide hints about the mechanism of recombination of H+2.Keywords
