Neutron Cross Sections at 115 ev and 300 ev—I

Total neutron cross sections for a number of elements were measured at 115 ev and 300 ev with an energy resolution of approximately 10 percent. The cross sections were separated into two parts: a resonance cross section and an asymptotic cross section. The first cross section represented the effect of a neutron resonance in the material studied overlapping the detector. The second cross section was identified either as the potential scattering cross section, or a minimum cross section in the neighborhood of a resonance.
