The problem of core hole localization in symmetrical systems is a fundamental problem of x-ray spectroscopy and concerns some basic aspects of quantum theory. Recent theoretical as well as experimental investigations of resonant x-ray Raman scattering indicate that the solution to this problem depends on the measurement. In the present work we propose an experimental scheme which allows a direct measurement of the atom to which the core hole is localized. The idea behind the proposal is based on the electron Doppler effect and the photoelectron-photoion coincidence technique.
