Structure of ²⁸Mg and influence of the neutron pf shell

NUCLEAR REACTIONS ¹²C(¹⁸O, 2p), E=48 MeV; measured Eγ, Iγ, γγ-coin, γ(θ), Ep, Ip, level half-lives by DSAM using the TIGRESS array and CsI(Tl) scintillator array for charged particle detection at ISACII-TRIUMF. ²⁸Mg; deduced levels, intruder orbitals, J, π, B(E2). Systematics of yrast states in ^24,26,28,30Mg, ³⁰Si, ³²S. Comparison with ab initio symmetry adapted no-core shell model (SA-NCSM) calculations using the SDPF-MU interaction, and with evaluated data in the ENSDF database.

NUCLEAR STRUCTURE ²⁸Mg; calculated levels, intruder orbitals, J, π, neutron occupancies in the pf shell, B(M1), B(M2), proton and neutron effective single-particle energies. Ab initio symmetry adapted no-core shell model (SA-NCSM) calculations using the SDPF-MU, USDB(sd) and SDPF(U) interactions. Comparison with experimental data.
