M020400100003 AUTHOR (A.Wataghin,R.B.Costa,A.M.Freire,J.Goldenberg) M020400100004 INSTITUTE (3BZLRIO,3BZLUSP) M020400100005 REFERENCE (J,NC,19,(5),864,1961) M020400100006 FACILITY (BETAT,3BZLUSP) M020400100007 INC-SOURCE (BRST) M020400100008 INC-SPECT The total dose was 990 r. M020400100009 METHOD (REC) M020400100010 SAMPLE A cylindrical target of Bi (thickness = 1.5 cm, M020400100011 diameter = 1 cm). M020400100012 DETECTOR (PLATE) A 400 mu thick Ilford C2 emulsions. M020400100013 PART-DET (P) M020400100014 ANALYSIS Data are normalized for equal scanned volumes. M020400100015 ERR-ANALYS (ERR-S) Statistical errors are presented. M020400100016 CORRECTION For: a) efficiency of the scanners(of the order of M020400100017 70%), M020400100018 b) back-ground(from 10 to 20%), M020400100019 c) geometrical losses, M020400100020 d) variation of (n,p) cross sections with energy. M020400100021 ADD-RES (THEO) The angular distributions can be described by M020400100022 the formula A+B*sin**2+C*cos. The average value of M020400100023 the ratio B/A is 0.68 with error 0.15 and the M020400100024 average value of C/A = 0.155 with error 0.056. M020400100025 COMMENT An excess of high energy neutrons over the M020400100026 evaporation spectrum existing at all angles was M020400100027 measured. M020400100028 The variation of B/A with energy was studied. The M020400100029 data indicate a maximum value of the ratio B/A M020400100030 around 5.5 MeV.
