Cross section calculations of photoabsorption and Compton scattering contributions to He single and double ionization via recoil momentum observable
This paper presents a theoretical framework for the calculations of Compton scattering and photoabsorption on bound electrons for single and double ionization, based on recoil-ion observable. For the photoionization of helium (single or double) our calculations of cross sections for photon energy of 7 keV show that the recoil ions from photoabsorption are mainly distributed on a sphere in momentum space of 22 a.u. radius, while recoil ions from Compton scattering show a dominant contribution close to zero radius ( < 3a.u.). Our calculated cross sections are in agreement with published experimental values.
