摘要

Abstract

Within the framework of isospin-dependent Boltzmann-Langevin model, the production cross sections of proton-rich nuclei with Z = 20-25 are investigated. According to the reaction results for different isospin of projectiles ,48,Ni,49,Ni, and ,50,Ni, proton-rich fragments tend to be more easily produced in reactions with the proton-rich projectile ,48,Ni. The production cross-sections of the unknown nuclei in the vicinity of the projectile are sensitive to incident energy. It is observed that incident energy of 345 MeV/u is appropriate for producing proton-rich nuclei with Z = 20-25. In projectile fragmentation reactions based on the radioactive ion beam of ,48,Ni at 345 MeV/u, several unknown proton-rich nuclei near the proton drip line are generated in the simulations. All these new nuclei are near-projectile elements near Z = 28. The production cross sections of the new nuclei ,34,Ca,37,38,Sc,38,Ti,40,41,42,V,40,41,Cr, and ,42,43,44,45,Mn are in the range of 10,-2, – 10,2, mb. Hence, projectile fragmentation of radioactive ion beams of Ni is a potential method for generating new proton-rich nuclei with Z = 20-25.
