摘要：

A simulation-optimisation algorithm (GABY code) is used for hydrogen determination in elastic recoil detection analysis (ERDA) induced by 1.8-3 MeV He-4 ions. The scattering cross section and the effect of straggling, multiple scattering and geometrical spreading are taken into account in the simulation. The capabilities of this absolute method (in transmission geometry) are briefly described in terms of sensitivity, probing depth and depth resolution. The hydrogen measurements are interpreted in relation to the damage induced by the He-4 microbeam. We show that the hydrogen distribution can change during the He-4 irradiation, depending on the local structure of the target material. The influence of large doses and the dose rate are discussed. This procedure has been applied using a nuclear microprobe to study the hydrogen distribution in thin polymer films irradiated by high energy heavy ions (Kr 230 MeV) and natural glasses.
