【 摘 要 】

It is demonstrated that recent experiments on ionization of 3p and 3s electrons in Ni film and solid body [1] cannot be described in the frames of Hartree-Fock or the random phase approximation with exchange. The deviation is so big that from the theoretical side it requires inclusion of huge and yet unknown effects.
