Abstract
In this work the absolute differential cross sections of the 18O(d,pγ)19O (Eγ = 1376 keV) ,18O(d,nγ)19F (Eγ = 1357 keV) and 16O(d,pγ)17O (Eγ = 871 keV) reactions were measured for the isotopic analysis of oxygen by DIGE technique. The energy of the incident deuterons was varied from 590 to 1994 keV in steps of 10 keV. Gamma-rays and backscattered deuterons were collected simultaneously by an HPGe detector at an angle of 90° and an ion implanted Si detector at a scattering angle of 165° with respect to the beam direction. An anodic Ta216,18O5 thin layer on tantalum was used throughout the cross sections measurement. The validity of obtained cross sections was checked by benchmarking experiment with a thick Y2O3 target. The overall systematic uncertainty of the measured cross section data was estimated to be better than 9%.
