C 103, 024004 (2021) M.D.Higgins, C.H.Greene, A.Kievsky, M.Viviani Comprehensive study of the three- and four-neutron systems at low energies NUCLEAR STRUCTURE 3,4n; calculated adiabatic hyperspherical potential curves for Jπ=3/2- for the 3n system and Jπ=0+ for the 4n system, phase shifts and eigenshifts using explicitly correlated Gaussian (CGHS) and the hyperspherical harmonic (HH) bases, multichannel analysis of the three-and four-neutron scattering near the scattering continuum threshold; deduced no evidence of a 4n-resonance at low energy. Discussed experimental result of possible 4n resonance by 2016Ki01 in 4He(8He, 4n8Be) reaction.
