NEUTRON LEAKAGE SPECTRA FROM Be, Al, Fe, Ni, Pb, LiPb, Bi, U AND Th SPHERES WITH T(d, n) AND 252Cf NEUTRON SOURCES

This paper presents the results of time-of-flight measurements of neutron leakage spectra from Be, Al, Fe, Ni, Pb, LiPb, Bi, U and Th spheres with central 14MeV neutron source and from U and Th sphere with 252 Cf source. Description of experimental set-up, measuring and correction procedures are given. The obtained data are discussed and compared with transport calculations and evaluated data files.
