2025-12-23 Dataset of Reexamined mass of 22C via the constraint from the recently experimental extraction of its radius doi:10.57760/sciencedb.j00186.00890 en Based on a constructed three-body model for the ²²C nucleus, this work systematically investigates its nuclear structure properties by applying the Faddeev method and developing a corresponding FaCE computational program. Under the constraint of the root-mean-square (r.m.s.) matter radius, the two-body and three-body interaction potentials are systematically adjusted. Orbital energy levels and corresponding two-neutron separation energies are obtained through calculation, and the results are visualized using Mathematica, thereby allowing determination of the spatial configurations of the ground and excited states as well as generating spatial density distribution plots of the valence neutrons.The dataset includes: the FaCE source code (see the cited references for its documentation), the prepared input files and corresponding output files (five sets in total, corresponding to the five datasets in Table 1 of the paper), and the Mathematica codes written to process the output data. The spatial distribution maps of valence neutrons and the spatial configuration results can be obtained directly within the Mathematica environment.
