Benchmarking the cross section for inelastic neutron scattering from <sup>193</sup>Ir

ORAL

Abstract

Neutron activation measurements of the 193Ir(n,n')193mIr reaction were performed at the Triangle Universities Nuclear Laboratory to resolve a longstanding discrepency between integral and differential measurements. Samples of natural iridium and enriched 193Ir were irradiated with monoenergetic neutron beams with energies of 4.6 and 6.0 MeV. The de-excitation of the metastable state at 80.2 keV in 193mIr was determined by means of measuring X rays following electron conversion. Special attention was paid in the data analysis to the X-ray attenuation in the samples. Results from our activation measurements will be reported.
