Configuration mixing in ²⁸Mg and the ²⁶Mg(t, p)²⁸Mg

NUCLEAR REACTIONS ³H(²⁶Mg, p)²⁸Mg, E=160.6 MeV; ²H(²⁶Mg, p)²⁷Mg, E=160.6 MeV; measured reaction products, particle-identification spectra, E(p), I(p), σ(θ) using HELIOS magnetic spectrometer and auxiliary detectors at the ATLAS-ANL facility. ²⁸Mg; deduced levels, J, π, L-transfers; calculated levels, J, π, proton- and neutron-occupation numbers for selected states in ²⁸Mg using shell model with SDPF-MU interaction. DWBA analysis of σ(θ) distributions. Comparison with previous experimental data in the ENSDF database. ²H(²⁶Mg, p)²⁷Mg reaction used for energy-calibration and transport-efficiency information. Relevance to sd-fp cross-shell excitations between the valley of stability and the 'island of inversion'.
