Abstract
A method of measuring the full differential cross section (FDCS) of single Compton ionization of a helium atom, which does not need detecting the scattered photon, has been presented in a recent paper published in the journal Nature physics [1]. The experimental data have been described within a theory based on the \({{A}^{2}}\) approximation. In the case of low (of the order of several keV) photon energies the model has given a good fit of the data. In the present paper, the possibility of studying the momentum distribution of the active electron in the target atoms with the help of such reactions is discussed in more detail.
