Measurement of reaction cross-sections for [sup.64]Ni [sup.58]Co at [E.sub.n] = 3.7 MeV

The reaction cross-sections for [sup.64]Ni(n, [gamma]) [sup.65]Ni at [E.sub.n] = 0.025 eV and [sup.58]Ni (n, p) [sup.58]Co at [E.sub.n] = 3.7 MeV have been experimentally determined using activation and off-line [gamma]-ray spectrometric technique. The thermal neutron flux used is from the thermal Column of the reactor AP-SARA at BARC, Mumbai, whereas the neutron energy of 3.7 MeV is from the [sup.7]Li(p, n) reaction at Pelletron facility, TIFR, Mumbai. The [sup.64]Ni(n, [gamma]) [sup.65]Ni and [sup.58]Ni(n, p) [sup.58]Co reactions cross-sections from present work are compared with the available literature data and found to be in good agreement. The [sup.58]Ni(n, p) [sup.58]Co 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.
