Cluster structure of a low-energy resonance in tetraneutron

NUCLEAR STRUCTURE ^2,3,4NN; calculated effective ²n-²n potential, eigenvalues, effective intercluster potential induced by the Rosenfeld interaction, phase shift of the elastic ²n-²n scattering in the coupled-channel approach, coefficients of the expansion of the continuum states of the ⁴NN system in the SU(3) basis; deduced that the tetraneutron has a good chance to exist as a compound system, where ³n+n and ²n-²n coupled cluster configurations coexist.
