  We present calculations of the total and m-fold electron-loss cross sections
using the DEPOSIT code for highly charged U(q+) ions (q=10,31,33) colliding
with Ne and Ar targets at projectile energies E=1.4 and 3.5 MeV/u. Typical
examples of the deposited energy T(b) and m-fold ionization probabilities Pm(b)
used for the cross-section calculations as a function of the impact parameter b
are given. Calculated m-fold electron-loss cross sections are in a good
agreement with available experimental data. Although the projectile charge is
rather high, a contribution of multiple-electron loss cross sections to the
total electron-loss cross sections is high: about 65% for the cases mentioned.
