    Nucleon-induced nuclear reactions are a significant field in nuclear physics with numerous applications like as in the production of medically important radioisotopes. The primary objective of this study is to analyze the excitation function of nucleon-induced nuclear reactions on the arsenic-75 isotope across projectile energies from 10 MeV to 100 MeV using COMPLET code. The excitation functions of the seven reaction channels: 75As(p, 3n)73Se, 75As(p, pn)74As, 75As(p, p5n)70As, 75As(p, p2p)73As, 75As(p, n)75Se, 75As(n, 2n)74As, and 75As(n, p)75mGe were investigated, analyzed and compared with experimental data within the energies from 10 MeV to 100 MeV. The calculated excitation functions showed strong agreement with experimental data obtained from the EXFOR data base, as assessed using Pearson’s correlation coefficient. Both pre-equilibrium and equilibrium nuclear excitation functions for all nucleon-induced reaction channels displayed a strong correlation with experimental results, except for the neutron-induced reaction channel, 75As(n, p)75mGe, which exhibited a moderate correlation. Studies have indicated that the pre-equilibrium reaction mechanism primarily governs the high-energy segment of the excitation function, whereas the low-energy segment is dominated by the equilibrium reaction mechanism for both neutron and proton-induced nuclear reactions on arsenic-75. Thus, utilization of the COMPLET code and the EXFOR data base has facilitated a detailed analysis of induced nuclear reactions in producing radionuclides with diverse applications.
