The variation of nuclear reaction cross-sections with the variation in projectile energies is called excitation functions has been a subject of great interest since last few decades. They beautifully display the pre-equilibrium as well as equilibrium emission of particles. Nucleon-induced reactions on medium-mass nuclei are important for nuclear-structure studies and isotope production. Selenium-80 is a target for producing bromine, arsenic, and germanium isotopes. The aim of this study is to compute and validate cross sections for key proton- and neutron-induced reactions on 80Se that produce 76,77Br, 76As, 77Ge, and 80As. Excitation functions for 80Se(p, 4n)77Br, 80Se(p, 5n)76Br, 80Se(p, α)76As, 80Se(n, α)77Ge, and 80Se(n, p)80As were calculated with the COMPLET code and compared to literature data. COMPLET reproduces the main features of the measured excitation functions, matching peak energies and magnitudes for most channels. The results of such calculations were compared to predictions of a well-established optical potential and with experimental data, reaching very good agreement. COMPLET reliably models the investigated reactions on 80Se and yields cross sections useful for isotope production and reaction studies. The results aid beam-energy selection and experimental planning for producing 76,77Br, 76As, 77Ge, and 80As and support further model refinement.
