(n,Z) reaction cross sections on stable, structural materials at fast neutron energies are important for understanding H and He production in fusion and Gen IV fission reactors. But for certain reactions, or at certain energies, data are sparse, and evaluated cross sections disagree. Improved measurements of exclusive cross sections and angular distributions are needed to inform evaluations. During the 2019 run cycle at the Los Alamos Neutron Science CEnter (LANSCE) Weapons Neutron Research (WNR) facility, the Low-Energy N,Z (LENZ) setup was used to measure double-differential (neutron energy, charged particle angle) cross sections for (n,p) and (n,a) reactions on 58,60Ni, for neutron energies ranging from ~1 – 20 MeV. The results of this measurement will also inform the analysis of recent LENZ measurements on unstable isotopes 56,59Ni. Preliminary results for 58,60Ni will be presented. LA-UR-21-26010
