Abstract

The spectral distribution of the neutron current behind U, U+W, U+Ge+Mn, U+Ge+Mn+W, Sc and Sc+Mn filter combinations has been investigated with high resolution transmission measurements in the energy range from 15 eV up to 500 keV. The time of flight technique and the 50 m total cross section beam facility of GELINA, running with 14 ns burst width, were used. The transmission, the energy positions, the widths and the areas of the observed “windows” have been calculated below 102 keV.
