Production cross section of neutron-rich isotopes with radioactive and stable beams

The production cross section of neutron-rich isotopes of Ca, Zn, Te, Xe, and Pt are predicted in the diffusive multinucleon 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.

The cross sections correspond to the maxima of the $0n$ evaporation channels (closed symbols) and $2n$ evaporation channels (open symbols). The symbols correspond to the indicated reactions. Arrows connect the points corresponding to the productions of the same isotope but in different evaporation channels.
