Description
Abstract: We describe how the energy shift for the Pauli-forbidden X-ray transitions is calculated within the Dirac-Fock theory. We start from the general expression for the cross-section of usual, Pauli-allowed, X-ray transitions and then explain what changes should be considered in the Pauli-forbidden case. The specific cases of copper (the material of choice for VIP experiment), lead and gold are described.
We finish the presentation with a brief methodological and philosophical discussion about the role of the time in these calculations and the role of the time in the antisymmetrization of the electrons
