With very few exceptions, direct measurements of neutron capture rates on radionuclides have not been possible. A number of indirect methods have been pursued, however, substantial effort has been devoted to quantify the usually large systematic errors that accompany the results from these techniques. A new instrument has been developed at the Los Alamos Neutron Science CEnter (LANSCE) to...
Accurate neutron capture rates for unstable nuclei are essential for nuclear data evaluations and for improving reaction network calculations. A promising approach combines radioactive ion beams with the Oslo method, which extracts nuclear level densities and γ-ray strength functions to indirectly constrain capture rates. The β-Oslo technique extends this capability to beam intensities down to...
