Abstract
Absolute cross sections have been measured for the excitation of hydrogen atoms to the , , and states by the impact of ground-state hydrogen atoms on He, Ne, Ar, , , and in the energy range from 10 to 35 keV. In this energy range the cross sections for the different angular momentum states are generally the same order of magnitude ( ). Excitation to the state is more competitive with the -state excitation at the level than at the level. Excitation to the state is not as likely as excitation to the or states. Cross sections for the production of Balmer radiation have been computed. Polarization fractions for the radiation have also been measured.
