Аннотация:Recent experiments on single and double ionization of atoms by Compton scattering potentially open the door to establishing new methods of dynamical spectroscopy complementing the well-known methods like (e,2e) and (e,3e) spectroscopy. In this paper we explore the possibility to use double ionization of the helium atom by Compton scattering as a tool for direct spectroscopy of electron-electron correlations. For rather high photon energies of a few dozens of keV, a non-relativistic theoretical description of the process and the Kramers-Heisenberg-Waller approximation can be consistently used with a high computational efficiency.
