Neutron resonance parameters of <sup>191</sup>Ir and <sup>193</sup>Ir

ORAL

Abstract

Neutron capture and neutron transmission measurements with isotopically enriched 191Ir and 193Ir samples were carried out at the Los Alamos Neutron Sciences Center with the DANCE and DICER instruments, respectively. Combining the neutron capture and transmission data sets and performing R-matrix analysis enables us to determine the neutron width and the total width of the resonances. The spins of the resonances were assigned using the gamma-ray multiplicity distribution. We will describe the experiments, data analysis, and report the obtained resonance parameters of 191Ir and 193Ir.
