“…The effective pairing interaction is treated in DFT in a phenomenological way with its strength fixed by a fit to experimental observables such as odd-even mass staggerings [3,10] or moments of inertia in rotating nuclei [11]. While in light nuclei the comparison with experiment in the vicinity of two-neutron drip line will be possible in future, the situation is different in medium and heavy mass nuclei for which the neutron drip line is located far away from existing or future experimental data.…”

The sources of theoretical uncertainties in the prediction of the two-neutron drip line are analyzed in the framework of covariant density functional theory. We concentrate on single-particle and pairing properties as potential sources of these uncertainties. The major source of these uncertainties can be traced back to the differences in the underlying single-particle structure of the various covariant energy density functionals (CEDF). It is found that the uncertainties in the description of single-particle energies at the two-neutron drip line are dominated by those existing already in known nuclei. Only approximately one third of these uncertainties are due to the uncertainties in the isovector channel of CEDF's. Thus, improving the CEDF description of single-particle energies in known nuclei will also reduce the uncertainties in the prediction of the position of two-neutron drip line. The predictions of pairing properties in neutron rich nuclei depend on the CEDF. Although pairing properties affect moderately the position of the two-neutron drip line they represent only a secondary source for the uncertainties in the definition of the position of the two-neutron drip line.
