M034200100013 METHOD (REC) M034200100014 PART-DET (P) M034200100015 DETECTOR (PLATE) 400 mu thick NIKFI JA-2 emulsions of 5*3 M034200100016 cm**2 size. M034200100017 CORRECTION Energy spectra were corrected for: M034200100018 (a) the variation of nuclear emulsion thickness; M034200100019 (b) the dependence of the n-p cross section on M034200100020 neutron energy; M034200100021 (c) the probability that proton tracks end outside M034200100022 the emulsion; M034200100023 (d) the background. M034200100024 ADD-RES (COMP) The evaporation model and the direct M034200100025 photoeffect model were used. M034200100026 COMMENT The energy distribution obtained in the present work M034200100027 contains most of the fast photoneutrons. It is shown M034200100028 that the neutron yield cannot be explained within M034200100029 the statistical theory.
