Evolution of single-particle structure near the N=20 island of inversion

NUCLEAR REACTIONS ²H(²⁸Mg, p)²⁹Mg, E=9.47 MeV/nucleon, [secondary ²⁸Mg beam from Si(p, X), E=1.4 GeV, followed resonant ionization by the resonance ionization laser ion source (RILIS), and mass separated and injected into an ion trap at the HIE-ISOLDE-CERN Linac facility]; measured E(p), I(p), σ(θ) using ISOLDE Solenoidal Spectrometer. ²⁹Mg; deduced levels, J, π, L-transfers, spectroscopic factors, vacancies deduced from summed spectroscopic factors, binding energies of single-particle centroids. Comparison with shell-model calculations. Detailed σ(θ) data are tabulated in the Supplemental Material.
