Measurement of the 114Cd(n,g) cross section using the Detector for Advanced NeutronCapture Experiments at LANL

ORAL

Abstract

The \textsuperscript{114}Cd nucleus can impact nondestructive assay techniques that utilize Cd for neutron absorption as well as nuclear astrophysics applications in the study of the s-process. A recent sensitivity study of s-process abundances found that the uncertainties of the cross section for neutron capture on \textsuperscript{114}Cd have a significant impact on final abundance uncertainties. Therefore, precise knowledge of the \textsuperscript{114}Cd(n,g)\textsuperscript{115}Cd cross section is critical across a large range of incident neutron energies. Additionally, information on \textsuperscript{115}Cd Photon Strength Function (PSF) is essential for improving the reliability of calculations investigating the nature of possible M1 strength in \textsuperscript{114}Cd and properties of nuclei far from stability. We will present preliminary results from the measurement of neutron capture cross section of \textsuperscript{114}Cd for incident neutron energies from 1 keV to 300 keV performed with the Detector for Advanced Neutron Capture Experiments (DANCE) at the Los Alamos Neutron Science Center.
