NEAR-THRESHOLD CORRELATIONS OF NEUTRONS

The emergence of charged-particle clustering in near-threshold configuration is a phenomenon which can be explained in the Open Quantum System (OQS) description of the atomic nucleus. In this work, we apply the realistic Shell Model Embedded in the Continuum (SMEC) to elucidate emergence of neutron correlations in near-threshold many-body states coupled to l = 1,2 neutron decay channels. Consequences of continuum coupling for spectra and the emergence of complex multi-neutron correlations are briefly discussed.
