Abstract: A good set of optical model potential parameters was established from the code APMN.FOR based on the experimental data of p+⁵⁹Co reaction. Excitingly, the parameters can be used widely in the nuclear reaction for ⁵⁹Co neighboring nuclides with proton of incident energy below 200 MeV, which can be seen from the calculation of the reaction ⁵⁶Fe, ⁵⁸Ni, ⁶³Cu with proton.
