摘要：

We study ground- and excited-state properties of all sd-shell nuclei with neutron and proton numbers 8 <= N, Z <= 20, based on a set of low-resolution two-and three-nucleon interactions that predict realistic saturation properties of nuclear matter. We focus on estimating the theoretical uncertainties due to variation of the resolution scale, the low-energy couplings, as well as from the many-body method. The experimental two-neutron and two-proton separation energies are reasonably well reproduced, with an uncertainty range of similar to 5 MeV. The first excited 2(+) energies also show overall agreement, with a more narrow uncertainty range of similar to 500 keV. In most cases, this range is dominated by the uncertainties in the Hamiltonian.
