M0509 1 18 COMMENT Using the betatron bremsstrahlung beam the yield of M0509 1 19 photoneutrons from the reaction 4-Be-9(g,n) and M0509 1 20 photoneutron spectra average energies were measured. M0509 1 21 The reaction cross section was obtained from the M0509 1 22 yield by the variable bin Penfold-Leiss method. The M0509 1 23 parameters of the resonances near (g,n) reaction M0509 1 24 threshold were deduced. M0509 1 25 CRITIQUE "Cross section of (g,n) reaction" is presented in the M0509 1 26 figs. 1 -3, not "photoabsorption cross section" as in M0509 1 27 captions.
