Average nuclear binding energies in a Lee-Wick type model

We find: (i) The Lee-Wick type relativistic mean-field theory with finite n ucleon size effect can reproduce the binding energies for all nuclei over t he nuclide table quite well. For 1654 nuclei, whose mass numbers range from 16 to 263 and charge numbers range from 8 to 106, the calculated binding e nergies are near to the corresponding experimental values with a systematic al deviation of about 5.74%. (ii) The lowering of the calculated nuclear ma sses, by including Coulomb energy into the variational calculations, is ver y small.
