Abstract

Cross sections differential with respect to the energy loss and scattering angle of the projectile have been calculated for ionization of atomic hydrogen by 75-keV proton impact using the classical trajectory Monte Carlo method. The results are compared with the experimental data measured by Laforge [Phys. Rev. Lett.PRLTAO0031-900710.1103/PhysRevLett.103.053201 103, 053201 (2009)] and Schulz [Phys. Rev. APLRAAN1050-294710.1103/PhysRevA.81.052705 81, 052705 (2010)], as well as with the predictions of several quantum-mechanical theoretical models. The analysis of the deviations between the classical and the quantum-mechanical results shows that the three-body fragmentation dynamics cannot be understood purely classically; for the description of the process the quantum-mechanical treatment of the interplay between the electron-projectile and the projectile-target-nucleus interaction is unavoidable.
