Low-Z shore of the "island of inversion" and the reduced neutron magicity toward ²⁸O

NUCLEAR REACTIONS ¹H, C(³⁰Na, ²⁹F), (³⁰Na, ²⁷F), E=228 MeV/nucleon, [secondary ³⁰Na beam from ⁹Be(⁴⁸Ca, X), E=345 MeV/nucleon primary reaction at RIBF-RIKEN facility]; measured reaction residues ^27,29F using BigRIPS and ZeroDegree spectrometers, Eγ, Iγ, (²⁷F)γ- and (²⁹F)γ-coin using DALI2 array for γ detection. One-proton and one-proton-two-neutron removal reactions on carbon and polyethylene targets. ^27,29F; deduced levels, J, π, binding energy. Comparison with calculations using the SDPF-M interaction, and correlation of ²⁹F and ²⁸O level spectra.
