Neutron resonance spectroscopy of ${}_{}{}^{113}{}_{}{}^{}\mathrm{In}$ and ${}_{}{}^{115}{}_{}{}^{}\mathrm{In}$

The neutron total cross section for natural indium was measured for ${\mathit{E}}_{\mathit{n}}$=25–500 eV with the time-of-flight method at the Los Alamos Neutron Scattering Center. The neutron capture reaction was studied on a highly enriched sample (99.99%) of ${}_{}{}^{115}{}_{}{}^{}\mathrm{In}$. A total of 47 previously unreported resonances were observed. The combination of the two measurements allowed assignment of the new resonances to ${}_{}{}^{113}{}_{}{}^{}\mathrm{In}$ or ${}_{}{}^{115}{}_{}{}^{}\mathrm{In}$. Resonance parameters were extracted for all of the neutron resonances observed.
