英文摘要	The effects on the Halpha line profile of non-thermal excitation and ionization of hydrogen by a 100 KeV-1 MeV proton beam have been investigated. Non-LTE Halpha line profiles have been calculated for the temperature distributions of semiempirical flares models F1 and F2 (Machado et al. 1980). For reasonable values of the beam energy flux and power index, the hydrogen lines are greatly strengthened. However, contrary to the case of an electron bombarded atmosphere, the line is not broadened, and no central reversal appears. These effects, alone or in conjunction with linear polarization measurements or Lyalpha red wing observations, can be used to diagnose proton beam bombardment.
