M050900100013 METHOD (EXTB,SITA) The reaction yield curve measurement. M050900100014 DETECTOR (BF3) 4PI neutron detector. M050900100015 ANALYSIS (PLA) The variable bin Penfold-Leiss method for cross M050900100016 section unfolding from the yield curve. M050900100017 ERR-ANALYS (DATA-ERR) Root-mean-squared uncertainties. M050900100018 COMMENT Using the betatron bremsstrahlung beam the yield of M050900100019 photoneutrons from the reaction 4-Be-9(g,n) and M050900100020 photoneutron spectra average energies were measured. M050900100021 The reaction cross section was obtained from the M050900100022 yield by the variable bin Penfold-Leiss method. The M050900100023 parameters of the resonances near (g,n) reaction M050900100024 threshold were deduced. M050900100025 CRITIQUE "Cross section of (g,n) reaction" is presented in the M050900100026 figs. 1 -3, not "photoabsorption cross section" as in M050900100027 captions.
