M028000100003 AUTHOR (A.De Marco,R.Garfagnini,G.Piragino) M028000100004 INSTITUTE (2ITYTUR) M028000100005 REFERENCE (J,NC/B,44,(1),172,1966) M028000100006 FACILITY (SYNCH,2ITYTUR) M028000100007 INC-SOURCE (BRST) M028000100008 REL-REF (I,,K.J.LE COUTEUR+,J,NP,13,32,1959) The technical M028000100009 details of the experimental arrangement. M028000100010 (N,,A.DE MARCO+,J,AAF,99,445,1965) Theoretical M028000100011 formula used in analysis of the experimental M028000100012 spectra. M028000100013 METHOD (REC) M028000100014 SAMPLE Bi and Pb, 5*4*1 cm**3. the 5 cm side parallel and M028000100015 the 1 cm, 4 cm sides perpendicular to the beam M028000100016 direction. M028000100017 DETECTOR (TRD) The helium gas-methyl alcohol vapors of the M028000100018 diffusion cloud chamber at 3 absolute atmosphere M028000100019 pressure. M028000100020 PART-DET (A) M028000100021 ERR-ANALYS (ERR-S) Statistical errors are presented. M028000100022 (E-ERR) The error of E is determined essentially by M028000100023 the error of the order of 2 % connected with the M028000100024 spatial reconstruction, taking into account also the M028000100025 finite dimension of the target, and by the M028000100026 range-energy relation. The error in the range-energy M028000100027 relation is assumed to be 3 %. M028000100028 CORRECTION Corrected for: M028000100029 i) tracks ending outside the sensitive volume of M028000100030 chamber, M028000100031 ii) the energy dependence of (n,alpha) elastic cross M028000100032 section. M028000100033 ADD-RES The neutron fraction for E > 2 MeV turns out to be M028000100034 0.03 with error 0.02 for Pb and 0.09 with error 0.03 M028000100035 for Bi. M028000100036 ANALYSIS The experimental energy spectra were analysed with M028000100037 the formula given by Le Couteur and Lang for the M028000100038 evaporative processes at high excitation energies.
