Effective interactions in the sd shell

NUCLEAR STRUCTURE ^{18,19,21,23,25,26,27}F, ^21,22,23,24O, ²²Na, ²⁴Mg, ^28,29Si, ³²S, ³⁹K; calculated levels, J, π, effective single-particle energies (ESPEs), B(E2) and Q(first 2+) for ²⁴Mg, ²⁸Si, ³²S. ^{16,17,18,19,20,21,22,23,24,25,26,27,28}O; calculated ground state energies relative to that of ¹⁶O, sub-shell gap and neutron spin-orbit splitting for even-A nuclei. No-core shell-model calculations with Okubo-Lee-Suzuki transformation, and microscopic effective shell-model interactions in the valence sd shell, obtained from chiral N3LO, JISP16, and Daejeon16 nucleon-nucleon potentials. Comparison with experimental data. Discussed possible role of the three-nucleon forces.
