M050900100026 COMMENT Using the betatron bremsstrahlung beam the yield of M050900100027 photoneutrons from the reaction 4-Be-9(g,n) and M050900100028 photoneutron spectra average energies were measured. M050900100029 The reaction cross section was obtained from the M050900100030 yield by the variable bin Penfold-Leiss method. The M050900100031 parameters of the resonances near (g,n) reaction M050900100032 threshold were deduced.
