Measurement of differential cross sections of deuteron elastic scattering on 31P for EBS purposes

Abstract The differential cross sections of deuteron elastic scattering on 31P were determined in the present work for the first time, in the projectile energy range Ed,lab = 900–2400 keV (in energy steps of ~10–30 keV), suitable for analytical purposes. The measurements were performed at the 5.5 MV TN11 HV Tandem Accelerator of N.C.S.R. “Demokritos”, Athens, Greece. The experimental setup consisted of five silicon surface barrier (SSB) detectors, placed at the angles between 130° and 170° (in steps of 10°) in a high-precision goniometer. The implemented target was a thin GaP layer evaporated on top of a thin carbon foil. The obtained differential cross-section datasets were benchmarked against a polished GaP crystal and the deviations from the corresponding ones using Rutherford’s formula will be discussed and analyzed.
