Measurement of reaction cross-sections for 64Ni(n, γ) 65Ni at En = 0.025 eV and 58Ni(n, p) 58Co at En = 3.7 MeV

The reaction cross-sections for 64Ni(n, γ) 65Ni at En = 0.025 eV and 58Ni (n, p) 58Co at En = 3.7 MeV have been experimentally determined using activation and off-line γ-ray spectrometric technique. The thermal neutron flux used is from the thermal Column of the reactor APSARA at BARC, Mumbai, whereas the neutron energy of 3.7 MeV is from the 7Li(p, n) reaction at Pelletron facility, TIFR, Mumbai. The 64Ni(n, γ) 65Ni and 58Ni(n, p) 58Co reactions cross-sections from present work are compared with the available literature data and found to be in good agreement. The 58Ni(n, p) 58Co reaction as a function of neutron energy is also calculated theoretically using TALYS computer code version 1.2 and found to be higher than the experimental data.
