Results of two experiments with Yttrium-89 samples on U/Pb-assembly "Energy plus Transmutation" [1] are presented. The assembly is a lead cylindrical target (8.4 cm diameter, 45.6 cm length) with natural uranium blanket (206.4 kg). The lead target was irradiated with JINR Dubna NUCLOTRON with 1.60 and 2.52 GeV deuteron beam. The final purpose of the experiments was to measure neutron field inside the assembly. Yttrium-89 activation detectors were located throughout the entire U/Pb-assembly. Irradiated sample gamma activity was measured with HPGe spectrometer. The gamma spectra were analyzed and the net peak areas were calculated using the DEIMOS program [2]. After short presentation of the activation results neutron spectrum determination method is proposed and its results presented.
