One-neutron removal from ²⁹Ne : Defining the lower limits of the island of inversion

NUCLEAR REACTIONS Pb(²⁹Ne, ²⁸Ne), E=244 MeV/nucleon; C(²⁹Ne, ²⁸Ne), E=240 MeV/nucleon, [secondary ²⁹Ne produced in ⁹Be(⁴⁸Ca, X), E=345 MeV/nucleon]; measured Eγ, Iγ, (²⁸Ne)γ-coin, inclusive longitudinal momentum distribution, one-neutron removal cross sections for ground and excited states of ²⁸Ne using BigRIPS separator and ZeroDegree spectrometer (ZDS) for particle detection and analysis, and DALI2 NaI array for γ detection at RIBF-RIKEN. ²⁸Ne; deduced levels, J, π, Coulomb dissociation cross sections. ²⁹Ne; deduced Jπ of ground state from longitudinal momentum distribution for ²⁸Ne. Comparison with large-scale shell model calculations using the SDPF-M effective interaction. Systematics of low-lying states of ^27,29,31Ne.
