In the paper, the authors present an account of the current status of laboratory measurements applicable to the interaction of fast protons and hydrogen atoms with the earths atmosphere. Data are also presented for some gases found in the atmospheres of other planets. After a brief discussion of recent measurements of the auroral particle energy spectra in order to define the energy range for relevant laboratory measurements, the motion of energetic protons in the atmosphere is discussed to eludicate further the cross sections and quenching processes of interest. A review of ionization experiments follows with emphasis on data acquired in the last decade. Cross sections for excitation of the atmospheric target gases and fast hydrogen projectiles are then presented. Application of the data to auroral calculations is also discussed. Author
