Wear measurement using radioactive tracer technique based on proton, deuteron and α-particle induced nuclear reactions on molybdenum

摘要

Excitation functions of light ion induced nuclear reactions on natural molybdenum have been studied in the frame of a systematic investigation of charged particle induced nuclear reactions on metals for various applications. Excitation functions of~ (93,94g,94m,95g,95m,96,99m)Tc.~(90,93m,99)Mo.~(90,91m,92m,95m,95g,96)Nb and ~(88,89)Zr were measured up to 50 MeV deuteron energy Tarkanyi et al., 2012 [1], ~(93m,93g,94m,94g,95m,95g,96g,99m)Tc, ~(90,93m,99)Mo, ~ (90,92m,95m,95g,96) Nb and ~(88,89)Zr were measured up to 40 MeV proton energy Tarkanyi et al., 2012 [2] and ~(93m,93g,94m,94g,95m,95g,96g,99m)Tc. ~(93m,99)Mo, ~(90)Nb, ~(94,95,97,103)Ru and ~(88)Zr were measured up to 40 MeV alpha energy Ditroi et al., 2012 [3] by using the stacked foil technique and activation method. The results for ~3He induced reactions on natural Mo were taken from the literature Comparetto and Qaim, 1980 [4]. According to their half-lives, from the above listed radionuclides the ~(95m,96)Tc, ~(91m,92m,95m,95g)Nb, ~(99) Mo, ~(103,97)Ru and ~(88)Zr are suitable candidates for wear measurement by using thin layer activation (TLA) method. The goal of this work was to determine the necessary nuclear data for TLA of the above radionuclides and to prove their applicability for wear measurements.
