Exploring nucleon-induced reactions on Selenium-80 using COMPLET code

Le résumé fourni par la source

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 80 Se that produce 76,77 Br, 76 As, 77 Ge, and 80 As. Excitation functions for 80 Se(p, 4n) 77 Br, 80 Se(p, 5n) 76 Br, 80 Se(p, α) 76 As, 80 Se(n, α) 77 Ge, and 80 Se(n, p) 80 As 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 80 Se and yields cross sections useful for isotope production and reaction studies. The results aid beam-energy selection and experimental planning for producing 76,77 Br, 76 As, 77 Ge, and 80 As and support further model refinement.
