abstract
18O induced radioactivation may be used for the trace detection of1H via1H (18O, n)18F. Matrices in which this reaction is interference-free include: Al, Si, S, K, Ti, V, Ni, Cu and Zn. However, due to numerous radioisotopes created at the bombarding energies used (E51 MeV), a post-irradiation chemical separation of18F is required.18O activation also appears as a promising means for the trace determination of S[S(18O, x)47V], Si[Si(18O, x)43-44Sc] and B[B(18O, x)37Mg]. 1979 Akadmiai Kiad.
