Activity measurement in Terbium-159 material using heavy ion beams

Abstract

Experiment has been performed to study the activity produced in the irradiation of Terbium-159 material with Oxygen-16 heavy ion beams using thin layer activation technique. The yields of reaction products 172,171,170Ta, 171,170Hf and 171,170,169Lu populated via various reaction channels have been measured in the Coulomb barrier to the well above it. A pre-calibrated high purity germanium detector has been used for γ-counting of material. The yield curves obtained from the study of intensity of characteristics γ-lines at different energies of heavy ion beam have been further used to determine the calibration curves of the obtained reaction products. An attempt has been made to study surface wear in terbium by applying heavy ion thin layer activation technique with increased sensitivity
