Neutron magicity in the proton drip-line nucleus ²⁰Mg: First invariant-mass reconstruction of ^{19, 20}Mg

RADIOACTIVITY ^19,20Mg(2p) [from ⁹Be(²⁴Mg, X)¹⁹Mg/²⁰Mg, E=170 MeV/nucleon]; measured decay products, Ep, Ip; deduced decay energies, excitation energies, and intrinsic widths of the resonant states, J, π, level scheme, R_4/2, persistence of N=8 shell around the proton drip-line. Comparison with shell model calculations, using the YSOX interaction, available data.
