Measurements of the total effective cross sections for resonance neutrons in Pd, Os, Ir, Mo, In, I, Ta, Th, U238

Abstract

The results of calculations of the level constants in the elements Pd, Os, Ir, Mo, I, In, Ta, Th, U238 are presented; the cross sections for these elements have been published earlier. New measurements for the cross sections in Ir, Th, U238 are cited. The measurements were made with a mechanical-chopper spectrometer with a resolution of 0.08 μsec/m in the energy region from 4.5 to 10,000 ev. The integrated and differential curves for the distribution of neutron widths in these elements are plotted.
