Investigation of the production routes of 81,82m,83,84 Rb isotopes through proton induced nuclear reactions on 82,83,84,86 Kr

Abstract Investigations using nuclear reaction models are significant and haveconsiderable consequences in terms of understanding nuclear reaction processes andtheir nature. The nuclear data of radionuclides created by the cyclotron findsapplication in nuclear diagnostics and therapeutic treatments. The excitationfunction of proton-induced nuclear reactions on 82,83,84,86 Kr for the generation ofmedically beneficial short-lived radioisotopes 81,82m,83,84 Rb from threshold energy to50 MeV has been investigated using Koning-Delaroche optical model potential withnuclear level density from both phenomenological and microscopic nuclear modelsincorporated in TALYS1.96 code. The phenomenological constant temperature+Fermigas model, back-shifted Fermi gas model, generalised superfluid model and microscopicnuclear level density from Skyrme–Hartree–Fock–Bogoliubov, Gogny–Hartree–Fock–Bogoliubov and temperature-dependent Gogny–Hartree–Fock–Bogoliubov nuclearlevel density tables have been used to calculate the excitation function. The calculatedexcitation functions are compared with the experimental data from EXFOR and theTALYS evaluated nuclear data library (TENDL2023). An analysis is carried out byestimating the mean deviation D-value between the theoretical and experimental crosssections and the nuclear level density model corresponding to the best result is usedfor the estimation of activity and production yield for each reaction channel.
