SS-HORSE–NCSM approach and its application to light nuclei

I present the SS-HORSE–NCSM approach for studying resonances in light exotic nuclei. This method extends ab initio No-Core Shell Model (NCSM) to continuum spectrum states. The SS-HORSE–NCSM have been utilized to describe resonant states in ⁵He, ⁵Li, ⁷He, ⁹Li and tetraneutron with realistic nucleon-nucleon interactions. This approach has been extended to three-body democratic decaying system and applied to search of resonances in the three neutron system with realistic nucleon-nucleon interactions very recently.
