AbstractAbsolute neutron capture cross sections for natural elements of scandium, titanium, rubidium, molybdenum, iodine, cesium, cerium, praseodymium, holmium, lutetium, and gold, and separated isotopes of190Os,192Os,194Pt, and238U are measured in the 0.5- to 3.0-MeV energy range. For most of these nuclides and isotopes, experimental data are scarce and discrepant, especially for rubidium,133Cs, cerium, lutetium, and194Pt, where no data are available above 0.6 MeV. Gamma-ray spectra emitted in the capture of 0.5-MeV neutrons, as well as the multiplicity of the gamma-ray transitions, are presented.
