64Zn is among the most tightly bound of all nuclides. It is about 49% of natural zinc. Note that 64Zn has even numbers of both protons and neutrons. Calculate
BE
A
,
the binding energy per nucleon, for 64Zn in MeV/nucleon. (Assume 1 u = 931.5 MeV/c2. Give your answer to at least three decimal places.)
