Binding energies of near proton-drip line Z = 22-28 isotopes determined
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, the lack of cross sections for isotopes in the 345A MeV 78Kr + 9Be is overcome by a newly discovered scaling phenomenon found in the 140A MeV 40;48Ca(58;64Ni) + 9Be reactions. The determined B are justified from obeying the scaling phenomenon of the difference between the mass of mirror nuclei. (2018-09-29)
