Two-particle density matrix evolution for atom at motion in solid film

The two-particle density matrix for hydrogen atom moving in carbon film is calculated. It is shown, that during the motion the particle states transformation to the localized ones, in the first the localization of the nucleus (proton) is began and only in the second after some time the progressive localization of the electron is began. The probability of the binding concentration between the electron and nucleus during the motion of the atom in the solid is calculated. The surviving fraction of the incident beam possess the enhanced Coulomb binding energy and the lowered energy losses as well
