摘要：

We have measured the Lyman-alpha-radiation following foil breakup of hydrogen ionic clusters H(n) + (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 H(n) + 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.
