The samples were in the G408600100015 form of an aluminum cylinder 8 mm high by 2 cm in G408600100016 diameter with 9 g of HfO2 powder for 17.5 MeV and a G408600100017 2.4x1.3x0.4 cm rectangular strip weighing about 13 g G408600100018 for 15.1 MeV. G408600100019 METHOD (ACTIV) Induced gamma-activity was measured. G408600100020 DETECTOR (GELI) The induced activity was measured using a gamma-G408600100021 spectrometers at the 1.8 -2 keV resolution for the Co60G408600100022 gamma-line 1.173 MeV. G408600100023 ERR-ANALYS (DATA-ERR) No information on sources of uncertainties. G408600100024 ADD-RES (COMP)Measured isomeric ratios were compared with G408600100025 values of model calculation TALYS-1.4 and EMPIRE-3.2 G408600100026 codes.
