Enhancement of Lyman-α radiation following foil-induced dissociation of fast ionic hydrogen clustersHn+

Abstract
We have measured the Lyman-α radiation following foil breakup of hydrogen ionic clusters Hn+ (n=2 and n=3 to 61, odd) with velocities above and around the Bohr velocity. An enhancement of this radiation was observed and could reach a factor of 3 with respect to the proton case of the same velocity. Cluster mass number, velocity, and thickness dependences of the relative population of the 2p state in hydrogen fragments following Hn+ foil dissociation have been extracted. A specific collective effect on the 2p-state hydrogen has been observed and interpreted in terms of charge-exchange processes.
