This data file compiles the results presented in P. Demol, U. Vernik, T. Duguet, A. Tichai, "Ab initio calculations of nuclear charge radii across and beyond ${}^{132}$Sn:Putting chiral EFT nuclear interactions to the test", Phys. Lett. B 878 140524 (2026). Each row in the file corresponds to different ab initio calculation and contains Hartree-Fock-Bogoliubov (HFB) and Bogoliubov coupled cluster at singles and doubles level (BCCSD) predictions of the total binding energy (E) and squared nuclear charge radius (Rch2). The column names correspond to : Nucl : symbol of the chemical element (here: Sn) Z : proton number (here: 50) N : neutron number A : mass number intID : identifier of the chiral EFT interaction freq : frequency of the spherical harmonic oscillator basis [MeV] (here : 12) eMax : truncation of the one-body basis (here : 12) Ehfb : HFB prediction of total binding energy [MeV] Ebccsd : BCCSD prediction of total binding energy [MeV] Ebccsdt : BCCSD[T] prediction of total binding energy, i.e. including the leading order correction of triple excitations [MeV] Rch2hfb : HFB prediction of squared nuclear charge radius [fm^2] Rch2bccsd : BCCSD prediction of squared nuclear charge radius [fm^2] Ehfb_hw+2 : HFB prediction of total binding energy for oscillator frequency (freq) + 2 MeV [MeV] Ehfb_hw-2 : HFB prediction of total binding energy for oscillator frequency (freq) - 2 MeV [MeV] Ehfb_eMax+2 : HFB prediction of total binding energy in one-body basis truncated at eMax + 2 [MeV] Ebccsd_hw+2 : BCCSD prediction of total binding energy for oscillator frequency (freq) + 2 MeV [MeV] Ebccsd_hw-2 : BCCSD prediction of total binding energy for oscillator frequency (freq) - 2 MeV [MeV] Ebccsd_eMax+2 : BCCSD prediction of total binding energy in one-body basis truncated at eMax + 2 [MeV] Rch2hfb_hw+2 : HFB prediction of squared nuclear charge radius for oscillator frequency (freq) + 2 MeV [fm^2] Rch2hfb_hw-2 : HFB prediction of squared nuclear charge radius for oscillator frequency (freq) - 2 MeV [fm^2] Rch2hfb_eMax+2 : HFB prediction of squared nuclear charge radius in one-body basis truncated at eMax + 2 [fm^2] Rch2bccsd_hw+2 : BCCSD prediction of squared nuclear charge radius for oscillator frequency (freq) + 2 MeV [fm^2] Rch2bccsd_hw-2 : BCCSD prediction of squared nuclear charge radius for oscillator frequency (freq) - 2 MeV [fm^2] Rch2bccsd_eMax+2 : BCCSD prediction of squared nuclear charge radius in one-body basis truncated at eMax + 2 [fm^2] twoj_valence_hfb : twice the total angular momentum of the valence shell at HFB level [hbar]
