Prediction for a four-neutron resonance

Abstract

We utilize various {\em ab initio} approaches to search for a low-lying resonance in the four-neutron ($4n$) system using the JISP16 realistic $NN$ interaction. Our most accurate prediction is obtained using a $J$-matrix extension of the No-Core Shell Model and suggests a $4n$ resonant state at an energy near $E_r=0.8$ MeV with a width of approximately $\Gamma =1.4$ MeV.
