Resumo

The Single-State HORSE (SS-HORSE) method is applied to studying resonant scattering. The method relies on microscopic calculations of nuclear spectra on the basis of the No-Core Shell Model with realistic nucleon-nucleon interactions and does not involve model approximations. The 3/2⁻ and 1/2⁻ resonances of the ⁵Li and ⁵He nuclei are investigated within the SS-HORSE method. The possible existence of a resonance in the four-neutron system is explored.
