Abstract

The benchmarking procedure in IBA (Ion Beam Analysis) regards the validation of charged-particle differential cross-section data via the acquisition of EBS (Elastic Backscattering Spectrometry) spectra from uniform thick target of known composition followed by their detailed simulation. In the present work such benchmarking measurements have been performed for the elastic scattering of protons on ²³Na, ³¹P and ^natS in the energy range of 1-3.5 MeV in steps of 250 keV at three backward angles, at 120.6, 148.8 and 173.5 in an attempt to validate the corresponding existing evaluated cross-section datasets from SigmaCalc and to facilitate their extension at higher energies. The EBS spectra acquired were compared with simulated ones using the DataFurnace code, along with an a posteriori treatment of the surface roughness. All the experimental parameters were thoroughly investigated and the results obtained and the discrepancies found are discussed and analyzed.
