Experimental determination of deuteron-induced activation cross sections of yttrium

Abstract

Excitation functions were measured for the89Y(d,x)90m,88,87m,87m+gY,89Y(d,x)88,89Zr and89Y(d,x)85Sr reactions in the energy range 9–40 MeV by the stacked-foil activation technique in combination with high resolution HPGe γ-ray spectroscopy. The data above 27 MeV have been measured for the first time. Yield calculations revealed that in the deuteron-induced activation of yttrium the direct production of88Y is about two times lower than that of88Zr. The maximum cross section for the production of the PET isotope89Zr by the Y+dprocess is higher than by Y+p. The yields and decay characteristics of the88Y and88Zr nuclides are suitable for thin layer activation (TLA) analysis.
