文摘

We measured cross-sections of the deuteron-induced reactions on ⁸⁹Y in the energy range of 3.9–19.5 MeV. Excitation functions for formation of ⁸⁸Zr, ^89mZr, ⁸⁹Zr, ⁸⁸Y, ^90mY and ^87mSr were determined and compared with previously published data and prediction of the TALYS code. Thick target yields for production of ⁸⁸Zr, ⁸⁹Zr^cum, ⁸⁸Y, ^90mY and ^87mSr were calculated from the measured cross-sections. Achievable activity versus radionuclidic purity of medically relevant ⁸⁹Zr is discussed and compared with the production via the ⁸⁹Y(p,n) reaction. Parallel use of titanium and aluminium beam monitors revealed systematic difference between the recommended cross-sections of both monitoring reactions and provided new cross-section data for formation of ²⁴Na, ²⁷Mg, ⁴³Sc, ^44mSc, ⁴⁴Sc, ⁴⁶Sc, ⁴⁷Sc and ⁴⁸Sc. The cross-sections for the ^natTi(d,x)⁴⁶Sc reactions agree very well with recently proposed recommended values.
