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.
