M031200100012 SAMPLE Cylindrical target of Bi-209. M031200100013 DETECTOR (PLATE) Type l4, thickness = 400 mu. M031200100014 PART-DET (P) M031200100015 CORRECTION The background was negligible. M031200100016 ERR-ANALYS (ERR-S) Statistical errors are presented. M031200100017 ADD-RES (COMP) Experimental spectra are compared with the M031200100018 evaporation theory. A contribution of high energy M031200100019 neutrons outside the evaporative curve divided by M031200100020 the total neutron number over E = 2 MeV is reported. M031200100021 The contribution of the photoneutrons arising from M031200100022 the Bi(gamma,2n) process is evaluated. M031200100023 COMMENT Photoneutron spectrum from Bi shows around 90 degrees M031200100024 a suprisingly high contribution of neutrons outside M031200100025 the calculated evaporative spectrum.
