The Study On Cross Section And Binding Energy Of Near Proton Drip Line Isotopes In Projectile Fragmentation Reactions At Intermediate And Relativistic Energies

The exotic properties of isotopes near the proton-drop line are constantly concerned in nuclear physics,such as the proton-skin and the proton-halo,the shell evolution,the proton emission etc.These properties of proton-rich isotopes are important for us to test models in extreme conditions and study the nuclear synthesis process in nuclear astrophysics.The experimental cross section and binding energy measured by radioactive ion beam facilities,which are one of the main methods to study properties of very proton-rich isotopes.However,it is difficult to measure the very proton-rich isotope experimentally because of the extremely short lifetime and low yield of them.Therefore,it is very sccential to accurately predict the cross section and binding energy of isotopes near the proton-drop line by the model or empirical formula,which is also of great significance for the experimental design and theoretical development in the future.The main work of this paper includes three empirical methods of predicting cross section or binding energy.Firstly,the exponential correlation relationship of the very proton-rich isotopes between cross section distribution and the binding energy is verified.By this exponential correlation,we can accurately predict the cross sections and binding energies of the very proton-rich isotopes.Secondly,square cross section is proposed by the analysis of the productions in the projectile fragmentation reactions the energies ranging from the fermi to the relativistic.Beside,a scaling phenomenon and the ability of prediction of the square cross section empirical formula has been studied.Finally,a new FRACS-C parameterization formula,basing on the FRACS parameterization,which has also been proposed.It can accurately predict the cross section of the proton-rich isotope.In conclusion,basing on the existing theory,this paper included empirical methods that can accurately predict cross section or binding energy of the proton-rich isotope.This not only provides reliable recommendations for subsequent experimental design,but also has important implications for the study of the nuclear structure and nuclear property near the proton-drop line.
