用活化和离线γ能谱技术测量了~（64）Ni（n，γ）~（65）Ni和~（58）Ni（n，p）~（58）Co在En = 0.025eV和En = 3.7MeV的反应截面。所使用的热中子通量来自孟买BARC的APSARA反应堆的热柱，而3.7 MeV的中子能量来自孟买TIFR的Pelletron设施的7 Li（p，n）反应。计算了~（64）Ni（n，γ）~（65）Ni和~（58）Ni（n，p）~（58）Co反应截面，并与文献数据进行了比较。用TDERS程序1.2版对~（58）Ni（n，p）~（58）Co反应随中子能量的变化进行了理论计算，计算值高于实验值。
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.
