Abstract

The total neutron cross sections for helium, carbon, nitrogen, oxygen and aluminium have been measured to an accuracy of 2% in the energy range of 80 to 150 MeV. Mono-kinetic neutron beams were used and the results are therefore free from the systematic errors associated with many earlier measurements. For carbon and aluminium the results are in excellent agreement with values obtained by time-of-flight techniques with good energy resolution. The oxygen cross sections are reasonably consistent with some earlier determinations at both ends of the energy range studied but are 10% smaller than some previous data in this energy range. The results presented for helium and nitrogen are in an energy region where few previous measurements have been made.
