On the doubly differential recoil-ion longitudinal momentum distributions from electron DDCS
Ionization is one of the most important reactions in ion-atom collisions. The doubly differential cross sections (DDCS), in energy and angle, for electron emission can provide a detailed understanding of the ionization dynamics. A general formulation for constructing the doubly differential recoil ion longitudinal momentum distribution from the measured electron DDCS is presented. This method allows one to obtain longitudinal recoil momenta without the use of a cold jet target. The complementary nature of the electron spectroscopy and the recoil-ion momentum spectroscopy is discussed. The authors use the energy and angular distributions of the electron DDCS in ionization of molecular hydrogen bombarded by bare carbon ions of energy 30 MeV. From these data they have derived the doubly differential electron and recoil ion longitudinal momentum distributions. The single differential distributions are also derived. In each case data are compared to CDW-EIS calculations.
