Investigating High-Energy Proton-Induced Reactions on Spherical Nuclei: Implications for the Pre-Equilibrium Exciton Model

“…Comparisons with the TENDL-2019 library [21] are also made. Additionally, the cross section measurements in this work are compared to the existing body of literature data, retrieved from EXFOR [2,12,[30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45].…”

“…A further motivation of this procedure is to avoid the compensating errors caused by current non-evaluation fitting methods that utilize too few experimental data and/or too simplistic parameter changes, which may ultimately hinder modeling as a whole. Particularly, simplistic or arbitrary parameter adjustments in TALYS, tuned to provide a better fit for a singular reaction channel of interest, are non-unique and may not hold a global physical basis because neighbouring reaction channels can suffer from the fit choice [12,14,16,41,42,49,[59][60][61][62][63]. Nevertheless, these adjustment methods are representative of a norm in non-evaluation modeling work and can have real-world implications such as incorrect predicted yields during medical radioisotope production, high level coproduction of an unwanted contaminant, or poor particle transport calculations.…”

Preequilibrium strength in light heavy-ion induced reactions up to 7 MeV/nucleon

“…The illustration by Maiti et al [16] suggested that the theoretical estimation of PEQ emission within the framework of the exciton model and geometry dependent hybrid model in different reaction codes, like TALYS and ALICE91, play a crucial role in emphasizing the production window of some medically relevant radionuclides. The excitation functions from 12 C+ 181 Ta and 187 Au, and 16 O+ 165 Ho and 181 Ta reaction reported by Cavinato et al [17] have mentioned that PEQ followed by EQ processes successfully reproduce the experimental data within or below 10 MeV/nucleon energy range. It has been explained by Birattari et al [18] that there is a reasonable change in the mean-field interaction between the nucleons with the change of energy, and they also have estimated the strength of PEQ emission in 12 C+ 103 Rh within 20 MeV/nucleon energy.…”

Sharma et al examined the PEQ emission from the 12 C and 16 O induced reactions on some medium mass targets within ∼7 MeV/nucleon energy range [4].…”

“…Fermi energy is provided by the two-body interaction between the nucleons of the composite system, and the rearrangement of energy between these nucleons takes place through the coupling between the translational momentum per nucleon of the colliding nuclei with their internal momentum [1]. The particle emissions in the PEQ process play a significant role in enhancing the production of residues in light and heavy-ion reactions [2][3][4][5][6][7][8][9][10][11][12][13][14]. The study gives an encyclopedic idea of those processes that occur during the deexcitation of nonequilibrated hot rotating nuclei created after a projectile-target interaction.…”
