INVESTIGATIONS OF EPITHERMAL NEUTRON SPECTRA BY MEANS OF THIN RESONANCE FOILS (UNTERSUCHUNG EPITHERMISCHER NEUTRONENSPEKTREN MIT DUNNEN RESONANZSONDEN),
Abstract
Using the resonance detectors 115In, Au, 152Sm, 186W, La, Mn, and 98Mo epithermal neutron spectra were studied at various points of the RFR core and in the vertical channel 2 of the RFR thermal column in the energy range 1 to 500 ev with respect to their deviations from 1/E behavior. In an air-filled channel at the periphery of the core, alpha = 0.98 + or - 0.02 was found by an absolute determination. The other measurements have been referred to this value. In the vertical channel 2 of the RFR thermal column (distance from the core boundary 60 cm), alpha = 1.04 + or - 0.02. (Author)
