Differential elastic backscattering cross-sections of the 1–2.4 MeV deuterons on sodium

Abstract The 23Na(d,d0)23Na elastic scattering differential cross-sections were measured in the energy range Ed,lab = 1060–2400 keV for elastic backscattering spectrometry (EBS) purposes. Thin sodium targets were used, made by evaporating Na2O powder on self-supporting carbon foils, with an ultra-thin Au layer on top for normalization purposes. The measurements were made with deuteron beam energy steps of 20 or 30 keV and for the laboratory scattering angles of 140°, 150°, 160°, and 170°. The determined cross-section datasets were benchmarked using a thick NaCl target at the deuteron energies (1110, 1320, 1500, 1820 keV) and at scattering angles 140°, 150°, 160° and 170°.
