An experimental investigation of Hydrogen isotopes interaction with Pd single-crystal surface has been carried out using molecular beam technique. The energy dependence of the sticking probability and its relation with the trapping probability into the precursor state is studied by integrating the scattered angular distribution of Hydrogen Isotopic defined beams from Pd{111} surface in the 40-400K surface temperature range. The dependence has been evaluated by defining Hydrogen molecular beams with different isotopic concentration – from natural one until 5% D/(D+H) and different incident energies and directed it onto a single-crystal Pd{111} surface. In the paper, we report the experiments results and some considerations related to its, have been made.
