Abstract

very high resolution neutron transmission measurements of enriched 58Ni and 60Ni samples were performed in the energy ranges 14eV up to 7.5MeV and 40eV up to 30MeV respectively. Time-of-flight and 1ns linac bursts were used to measure neutron energies. Total cross section data from 3 sample thicknesses have been analysed with an R-matrix multi-level code to deduce parameters of 72 resonances in 58Ni and 208 in 60Ni up to 305 and 550keV respectively, and the s-wave strength functions and average level spacings.
