Description
To further strengthen our understanding of nuclear reactions underpinning astrophysics, next-generation reactor designs, and national missions, we expanded reaction measurements on both stable nuclei and radionuclides. At Los Alamos Neutron Science Center (LANSCE), we perform direct measurement of the (n,p) and (n,$\alpha$) reaction cross sections using the LENZ (Low Energy NZ) instrument. We have been working to improve outgoing charged particles’ angular distributions and energy spectra by validating measured cross sections with theoretical predictions. Key results from the measured differential cross sections of $^{35}$Cl, $^{39,40}$K, $^{54,56}$Fe, and $^{56,58,59,60}$Ni will be presented and compared with Hauser-Feshbach model calculations, with particular emphasis on radionuclides, $^{40}$K, $^{56}$Ni and $^{59}$Ni. I will conclude with the ongoing effort of developing the optimized solenoid spectrometer at LANSCE for improving the fidelity of directly measured reaction data on radionuclides.
This work benefits from the LANSCE accelerator facility and is supported by the U.S. Department of Energy under contract No. 89233218CNA000001, the Laboratory Directed Research and Development program of Los Alamos National Laboratory under project numbers 20130758ECR and 20180228ER, and the US Nuclear Data Program under U.S. Department of Energy Office of Science-Nuclear Physics.
