G403500100014 Incident electron flux instability did not exceed 2%. G403500100015 A tantalum converter with a thickness of 1.05 mm was G403500100016 installed at the output of the electron accelerator; G403500100017 an aluminum electron moderator with a size of diameter G403500100018 90x100 mm was situated behind the converter. The G403500100019 distance from the Ta converter to the Al moderator was G403500100020 20 mm, and the distance to the studied sample was G403500100021 200 mm. G403500100022 SAMPLE Samples of metallic zirconium in the form of a powder G403500100023 with a mass of 206.36 mg, enriched with the 90Zr G403500100024 isotope, and zirconium oxide with a mass of 463.9 mg, G403500100025 enriched with the 91Zr isotope, were used for G403500100026 irradiation. G403500100027 METHOD (ACTIV) Induced gamma-activity was measured. G403500100028 DETECTOR (HPGE) Resolution of 1.9 keV for Co-60 line 1332 keV. G403500100029 ADD-RES Experimental data are compared with theoretical G403500100030 predictions calculated with TALYS code. G403500100031 ERR-ANALYS (ERR-S) The uncertainties include contributions from G403500100032 photopeak efficiency calibration, abundance, geometry G403500100033 configuration and intensities of gamma-rays (photopeak G403500100034 areas). Statistical uncertainties of photopeak areas G403500100035 made the main contribution to total uncertainty of G403500100036 result, the other errors are negligible.
