Differential cross-section measurements for deuteron elastic scattering on ~(nat)Si for elastic backscattering purposes

摘要

The differential cross sections of the Si-nat(d,d(0)) elastic scattering were determined at six backscattering angles, 120 degrees, 130 degrees, 140 degrees, 150 degrees, 160 degrees and 170 degrees. Two experiments were performed, one for the determination of the crosssection values and one for the validation of the obtained results. In the first experiment, a thin Si3N4 target with a thin layer of Au evaporated on top was bombarded with deuterons in the energy range between 1000 and 2200 keV in steps of 10 keV. In the benchmarking experiment, a thick Si [1 1 1] polished crystalline wafer target with a thin Au layer evaporated on top was irradiated with deuterons at E-dJab = 1300, 1600, 1900 and 2200 keV and at four scattering angles (130 degrees, 140 degrees, 150 degrees, 160 degrees).
