Abstract

Excitation functions were measured by the activation method using stacked-foil technique for the ^natSr(p,xn)^{88,87m,g,86m,g}Y reactions up to 18 MeV. The experimental results were compared with the theoretical data from EMPIRE-3.2 code and TENDL. Integral yields of ^{88,87m,g,86m,g}Y were estimated based on the measured cross sections. The optimum energy range for the production of the important isotope ⁸⁸Y is Ep = 16→11 MeV, ⁸⁸Y yield amounts to about 3 MBq/µAh.
