The trajectories of 200 to 400 keV protons in 5 to 18 nm thick gold foils are simulated by means of Monte‐Carlo calculations. The impact‐parameter distributions of ion–atomic collisions at different emission angles are obtained. The impact‐parameter distributions of the mean energy transfered to the atom at given emission angles are calculated. The angular dependence of the mean energy loss is also calculated. By fitting the latter with experiment the impact‐parameter dependence of the energy transfer in a single collision is obtained.
