Abstract

The classical trajectory Monte Carlo method has been used to calculate H+ + H(1s) electron capture and ionization differential cross sections at energies of 25-200 keV. Angular scattering of the electron removed by the ionization process has been studied as a function of ejected electron velocity νe. The classical calculations are in reasonable agreement with coupled-channel results for the "electron capture to the continuum" (ECC) component of the ionization process where this term is defined as the ejected electron being more closely centered to the projectile than the target nucleus after the collision. The ECC cross section σECC was studied as a function of collision energy (50-500 keV/amu) and projectile charge state (q=1 to 10). At high energies, σECC scaled as q2.3 E2.5. The maximum value for σECC was found at an energy Emax≅(56 keV/amu) q0.4. © 1983.
