MeV up to 52.5 M031900100009 MeV. M031900100010 INC-SPECT The gamma-beam impulse length was close to 0.5 microsecM031900100011 the period following the impulse was close to M031900100012 13 millisec. M031900100013 MONITOR The calibration was made by using threshold of M031900100014 (gamma,n) reaction for Bi-209, Co-59, C-12 nuclei and M031900100015 maximum position for the reaction O-16(gamma,p)n-15. M031900100016 METHOD (EXTB,SITA). The neutron yield was measured for M031900100017 different value of end-point energy of bremsstrahlung M031900100018 beam. M031900100019 PART-DET (N) The neutrons were slowed down to the thermal M031900100020 energy. M031900100021 DETECTOR (BF3). 12 BF3-counters were used, which where placed M031900100022 parallelly to the beam axis. M031900100023 SAMPLE Thickness was near to 17 g/cm-sq. M031900100024 ADD-RES (THEO) The data of this experiment agree with M031900100025 theoretical calculations wade without any M031900100026 assumption about the final state of the nucleus. M031900100027 (COMP) With experimental data of early measurements. M031900100028 ERR-ANALYS (ERR-S) Statistical errors are presented only. M031900100029 COMMENT The yield curve was measured with step 0.25 MeV in M031900100030 the energy range from the threshold up to 26.5 MeV, M031900100031 and with step 1.0 MeV in the energy range from the M031900100032 threshold up to 52.5 MeV. M031900100033 The cross sections were calculated by using M031900100034 inverse matrix method (Penfold-Leiss).
