The developed mathematical formalism is based on the multiconfiguration generalization of the nonrelativistic quantum theory of contact inelastic scattering of a photon by an atom, constructed in the work by Hopersky and Nadolinsky (2012 <em>J. Exp. Theor. Phys.</em> <strong>115</strong> 402).</p> nonrelativistic quantum theory;Mn atom;compton;photon;giant autoionization resonance;ev;Atomic Physics;Molecular Physics 2013-07-10
