  The production cross section of neutron-rich isotopes of Ca, Zn, Te, Xe, and
Pt are predicted in the diffusive multi-nucleon transfer reactions with stable
and radioactive beams. With these isotopes one can treat the neutron shell
evolution beyond N = 28, 50, 82, and 126. Because of the small cross sections,
the production of nuclei near the neutron drip line requires the optimal choice
of reaction partners and bombarding energies.
