Total Fast Neutron Cross Sections of Co, Ga, Se, Cd, Te, Pt, Au, Hg, and Th

Abstract

The total neutron cross sections of Co, Ga, Se, Cd, Te, Pt, Au, Hg, and Th were measured as a function of neutron energy from 0.1 to 3 Mev. An estimate of the error caused by neutrons scattered into the detector was made by measuring the apparent cross section as a function of sample diameter. The results give additional evidence that, neglecting resonance structure, total structure, total neutron cross-section curves have characteristic shapes which change slowly with atomic weight.
