“…For polycrystalline samples, a simple model to evaluate the angular dependence of the energy loss of low-energy protons was proposed and successfully compared with experimental data of 9-keV protons transmitted through thin aluminium and gold films [7]. The measured angular distributions were well described by the multiple-scattering formalism of Ref.…”

“…Since the early 2000s several studies of the angular distributions and of the angular dependence of the energy loss of low-energy light ions have been published [7][8][9][10]. For polycrystalline samples, a simple model to evaluate the angular dependence of the energy loss of low-energy protons was proposed and successfully compared with experimental data of 9-keV protons transmitted through thin aluminium and gold films [7].…”

Measurements of angular distributions and of the angular dependence of the energy loss of 4-, 6-, and 9-keV protons transmitted through thin Cu and Ag polycrystalline foils are presented. By means of standard multiple-scattering model calculations it is found that a V (r) ∝ r −2.8 potential leads to significantly better fits of the angular distributions than the standard Thomas Fermi, Lenz-Jensen, or Ziegler-Biersack-Littmark potentials. A theoretical model for the angular dependence of the energy loss based on considering geometric effects on a frictional inelastic energy loss plus an angular-dependent elastic contribution and the effects of foil roughness reproduces the experimental data. This agrees with previous results in Au and Al, therefore extending the applicability of the model to other metallic elements.

The angular distributions of protons travelling through thin polycrystalline gold targets (~15 nm) with incident energies in the range of 4-10 keV have been measured. The results confirm previous experiments at higher energies showing deviations from theoretical predictions based on the standard multiple scattering theory. In order to prove that the effect of crystal structure is one of the main causes of these deviations we have performed numerical simulations. To simulate the polycrystalline structure in a realistic way, we have made an analysis of the target by means of transmission electron microscopy (TEM) techniques. Including these characteristics in the simulation, together with the effect of vibrations and crystal disorder we analyzed the corresponding angular distribution. To evaluate the role of channeling, we also measured angular distributions of protons in a 〈100〉 gold foil and made the corresponding numerical simulations. The results show the critical influence of the target structure in the angular spectra of transmitted ions.
