Abstract: The yield of prompt γ-rays produced by interaction of 14 MeV neutrons with natNi was measured using the time-of-flight technique. A differential cross section from (n, xγ) reactions was unfolded from amplitude spectrum. Experimental results were compared with theoretical calculations performed using EMPIRE 3.2 and TALYS 1.6 codes. The effect of average characteristics of nuclear excited states on calculated gamma ray spectrum was studied.

Keywords: fast neutrons, time-of-flight method, gamma-ray spectrum, Hauser - Feshbach model, photon strength function, nuclear level density.
