Abstract

The assessment of an alpha -particle optical model potential for nucleon–induced alpha -emission within the Asim 60 mass-number range [Avrigeanu and Avrigeanu (Eur. Phys. J. A 57:54, 2021)] is completed by analysis of neutron–induced reactions on stable Ni isotopes. The same consistent set of nuclear–model input parameters as well as first uncertainty analysis of calculated cross sections related to the accuracy of independent data formerly used within parameter setting up have been concerned. Description of absorption and emission of alpha -particles by the same potential is validated, while the pickup direct reaction and Giant Quadrupole Resonance (GQR) alpha -emission beyond the statistical predictions are confirmed by recent data around the GQR energies.
