Experimental determination of deuteron-induced activation cross sections of yttrium

Keywords: Yttrium, Deuteron, Activation cross section, Cyclotron, Excitation function

Excitation functions were measured for the ⁸⁹Y(d,x)^{90m,88,87m,87m+g} Y, ⁸⁹Y(d,x)^88,89Zr and ⁸⁹Y(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 of ⁸⁸Y is about two times lower than that of ⁸⁸Zr. The maximum cross section for the production of the PET isotope ⁸⁹Zr by the Y+d process is higher than by Y+p. The yields and decay characteristics of the ⁸⁸Y and ⁸⁸Zr nuclides are suitable for thin layer activation (TLA) analysis.
