Multiple ionization processes of fast heavy low-charged ions in collisions with neutral atoms are considered. Combining the energy deposition model and the statistical probabilities for m-electron ionization, a new computer DEPOSIT code was developed for the calculation of multiple ionization probabilities and cross sections of heavy low-charged ions colliding with neutral atoms. A comparison of the present calculations for ionization of heavy ions (Xe18+, U28+) by various atoms at energies E > 1 MeV u(-1) with experimental data and the classical-trajectory Monte Carlo (CTMC) calculations shows that the suggested model can be applied with an accuracy of a factor of 2.
