  It is demonstrated that recent experiments on ionization of 3p and 3s
electrons in Ni film and solid body 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 not
entirely understood effects. Perhaps, it requires also experimental efforts in
order to clarify the prominent difference obtained for films and crystal
samples.
