Abstract
The spin assignments of 14 low-energy neutron resonances in Sb, Ta, Re, and Ir have been made by observing the transmission of polarized neutrons through polarized targets. The nuclei of diamagnetic atoms were polarized by dissolving them in iron, placing the alloy in a magnetic field, and reducing the temperature below 0.1°K. No correlation was found between the resonance spin states and the total radiation widths. Information has also been obtained on the magnitude and direction of the hyperfine fields at the solute nuclei.Keywords
