ELECTRON-NUCLEAR DYNAMICS OF PROTON COLLISIONS WITH METHANE AT 30 EV

The reactive collisions of protons with methane molecules at 30 eV in the laboratory frame are studied with the electron nuclear dynamics (E ND). The results from this theoretical approach, which does not invoke the Born-Oppenheimer approximation and does not impose any constraint s on the nuclear dynamics, are compared to the results from time-of-fl ight measurements. Total differential cross sections and integral cros s sections as well as fragmentation ratios and energy loss spectra are discussed. (C) 1997 American Institute of Physics.
