摘要/Abstract

摘要： Three-Coulomb-wave (3C) model is applied to study the single ionization of helium by 2 MeV/amu C⁶⁺ impact. Fully differential cross sections (FDCS) are calculated in the scattering plane and the results are compared with experimental data and other theoretical predictions. It is shown that the 3C results of the recoil peak are in very good agreement with experimental observations, and variation of the position of the binary peak with increasing momentum transfer also conforms better to the experimental results. Furthermore, the contributions of different scattering amplitudes are discussed. It turns out that the cross sections are strongly influenced by the interference of these amplitudes.
