abstract

  • Both7Li and10B induced radioactivation were applied to trace determination of hydrogen via the1H(7Li,n)7Be and1H(10B, )7Be reactions. In both cases, boron and magnesium present nuclear interferences, but their extent does not exceed 0.5%. At the bombarding energies used, 21 MeV7Li++ and 27 MeV10B++ the detection limits are respectively 2 and 0.5 ppm for an iron matrix irradiated for two hours. Due to the recoil of7Be, the samples were carefully prepared to avoid superficial hydrogen contamination. A series of samples which hydrogen content ranges from 15 to 120 ppm was examined, and the results obtained with the two beams were compared. 1985 Akadmiai Kiad.
