Study for radioisotopes (RIs) production using accelerator neutron sources plays an important role in development of production method to supply stably high-purity RIs for medical use.
We measured yields of several isotopes in Nb and ZnO samples irradiated by neutrons from 9Be(d,n) reaction with 40-50 MeV deuterons, and developed a powerful method to estimate the yields using a general purpose Monte Carlo particle transport simulation mode PHITS with cross section data of the (d,n) reaction and JENDL-4.0/HE.
We will show good agreement between new measured yields and estimated results. Furthermore, we will report a very interesting observation that yields of some RIs are enhanced by covering the samples with polyethylene blocks.
