Measurements of 60Ni(p,n)60Cu reaction cross-sections and covariance analysis of the uncertainty


The cross sections of the 60Ni(p,n)60Cu reaction from threshold energy to ~ 20 MeV have been measured by employing stack foil activation technique and off-line γ-ray spectrometry. The uncertainties for the reaction cross sections have been estimated by applying covariance analysis and least square method. The measured cross-sections are found to be in agreement with most of the literature data available in EXFOR database. The excitation function of the 60Ni(p,n)60Cu reaction was also theoretically calculated by using the TALYS-1.9 code. The excitation functions of 60Ni(p,n)60Cu reaction from TALYS-1.9 and TENDL-2017 follow a similar trend as of the experimental data of present work and literature but are little higher around the peak cross-section region.
