Abstract
An arrangement is described to produce a neutral hydrogen beam by splitting an accelerated H +2 -Ion in a gas target. At 500 keV energy of the neutral H-atom, the ratio of H +2 -ions to neutral H-atoms is measured to be about 12%. In the energy domain of 300 to 650 keV this ratio decreases only very little with increasing energy. The cross sections σ1, σ2 and σ3 for splitting inH ++H°, 2H ++e − and for electronloss of the neutral atom are given.
