Observation of three-neutron sequential emission from ²⁵O^*

NUCLEAR REACTIONS ²H(²⁷Ne, 2p)²⁵O^*, E=101.3 MeV/nucleon, [secondary ²⁷Ne beam mixed with other light nuclei from fragmentation of 140 MeV/nucleon ⁴⁸Ca primary beam from the Coupled Cyclotron Facility, and separated by A1900 Fragment Separator at NSCL-MSU]; measured E(n), ²²O fragments, (²²O)n-coin, four-body (²²O+3n), three-body (²²O+2n), and two-body (²²O+1n) ungated and gated decay-energy and hit-multiplicity spectra using the Modular Neutron Array (MoNA) and Large multi-Institutional Scintillator Array (LISA); deduced mass of ²⁵O from the invariant of the sum of the energy-momentum four-vectors of an ²²O fragment and the three associated neutrons emitted from the excited states of ²⁵O. ²⁵O; deduced neutron-unbound levels, resonances, decay via three-neutron sequential emission to levels in ²⁴O, ²³O and ²²O. Comparison with shell-model and eikonal calculations for two-proton removal reaction from ²⁷Ne.

NUCLEAR STRUCTURE ^23,24,25O; calculated levels using Gamow shell model with the density-matrix renormalization-group (GSM-DMRG) method, and a continuum shell model (CSM). Comparison with experimental data.
