A theory of the electron loss of an ion passing through a crystal in random orientation is developed for three mechanisms of ion–electron interaction with the crystal: 1) coherent atomic interaction with the crystal lattice without phonon production; 2) incoherent atomic interaction with crystal phonon energy changing; 3) electron–electron interaction with crystal electron energy changing. It is shown that under certain conditions any of the mechanisms considered can be dominant in the process of electron loss from the ion. It is also shown that for a multiply charged ion passing through the crystal an abnormal dependence of the ionization probability on the amount and direction of the ion velocity can occur.
