In this paper, the yields for the ionization and excitation from each molecular orbital of a water molecule irradiated by 10 keV electrons were calculated using the classical binary-encounter approximation.Abstract:
The yields for the ionization and excitation from each molecular orbital of a water molecule irradiated by 10 keV electrons were calculated using the classical binary-encounter approximation. On further assuming fragmentation processes of the excited or ionized states consistent with the photochemical and mass spectrometrical results in the literature, we obtained, as the radiolysis yields of water vapor: G(electron)=2.96; G(OH−)=0.04; G(H3O+)=3.00; G(H)=4.83–5.21, including G(‘hot’ H-atoms)≤0.87; G(H2)=0.28–1.15; G(O)=0.83–1.21; G(OH)=6.70–7.08, and G(–H2O)=G(ionized water)+G(excited water)=2.91+4.96=7.87.read more

Two-Particle Collisions. II. Coulomb Collisions in the Laboratory System of Coordinates
TL;DR: In this article, the energy and angular relations for two-particle collisions and the cross sections related to them are derived and presented explicitly in the laboratory system of coordinates, which should prove to be both sufficiently exact for the majority of calculations and at the same time fairly simple.
