The total neutron cross-sections of cobalt, silver, iodine, aluminium, nickel and gallium between 1 eV and 5 keV

Abstract

This paper presents experimental results of total neutron cross-section measurements made with a neutron time of flight spectrometer at the Atomic Energy Research Establishment, Harwell. Six elements, Co, Ag, I, Al, Ni and Ga, have so far been studied over the range of neutron energies from 1 eV to 5 keV. The main interest of the measurements lies in the use of improved resolution at the higher energies with the result that certain levels have now been more clearly resolved. The results are presented as curves showing the variation of total cross-section with neutron energy. For certain levels, the strength of the resonance is calculated. The spectrometer is briefly described and some reference made to previous work in the same field.
