Abstract
Theγ-radiation emitted after thermal neutron capture in isotopically enriched58Ni and60Ni was measured at the ILL high flux reactor by means of Ge/NaI detectors operated in Compton suppression and pair spectrometer mode. The neutron binding energies were determined asB n (59Ni)=8999.15(23) keV and Bn(61Ni)=7820.07(20) keV; some 95% of the totalγ-ray fluxes through59,61Ni were assigned. Theγ-ray strength functions of the primary transitions and the level densities are discussed.
