Charge-state dynamics of 1.4- and 11-MeV/u uranium ions penetrating H2 and He gas targets

Charge-changing cross sections and dynamic characteristics of 11-MeV/u uranium ions passing through He and H2 targets are calculated as well. Calculated equilibrium mean charge states q¯(He)=67.8 and q¯(H2)=75.7 are in agreement with RIKEN experimental data within 10%.
