Abstract：
A method is proposed to determine the one-neutron S_n or two-neutron S_2n separation energy of neutron-rich isotopes. Relationships between S_n (S_2n) and isotopic cross sections have been deduced from an empirical formula, i.e., the cross section of an isotope exponentially depends on the average binding energy per nucleon B/A. The proposed relationships have been verified using the neutron-rich copper isotopes measured in the 64A MeV ⁸⁶Kr + ⁹Be reaction. S_n, S_2n, and B/A for the very neutron-rich ^{77, 78, 79}Cu isotopes are determined from the proposed correlations. It is also proposed that the correlations between S_n, S_2n and isotopic cross sections can be used to find the location of neutron drip line isotopes.
