Charge Changing Processes in Hydrogen Beams

Charge changing processes of hydrogen beams in gases (${\mathrm{H}}_2$, He, ${\mathrm{N}}_2$, ${\mathrm{O}}_2$, Ne, Ar, Kr, Xe), atomic hydrogen, alkali metal vapors (Li, Na, Mg, K, Cs), and gaseous carbon are reviewed primarily from an experimental point of view. Following a simple description of charge changing phenomena and typical techniques of measurement, problems associated with the experiments are discussed. Experimental cross-section results for the various charge changing processes are presented in figures with critical comments. A brief review of the theoretical developments relevant to the charge changing processes of hydrogen beams is also presented.
