Abstract
A new method is proposed to determine the binding energy（B）of near proton-drip line isotopes from isotopic cross section distribution.To determine B of Z=22-28 isotopes（with Tz=-2 and-5/2）,the lack of cross sections for proton-rich isotopes in the 345A MeV78Kr+9Be is overcome by predicting the proton-rich isotopes from a newly discovered scaling phenomenon found in the proton-rich isotopes measured in the 140A MeV40,48Ca(58,64Ni)+9Be reactions.The cross sections for proton-rich isotopes are verified to exponentially depend on the average binding energy per nucleon,based on which B of the Z=22-28 isotopes with Tz=-2 and-5/2 are determined from cross sections.The determined B of the isotopes are justified from obeying the scaling phenomenon of the difference between the mass of mirror nuclei.The cross sections for the Z=22-28 isotopes with Tz=-1 and-3/2,which in potential can be experimentally studied in mass storage ring,are also predicted.
