    "abstract": "The cluster reduction method for the Yakubovsky equations in configuration\nspace is used for calculations of zero-energy scattering in four-nucleon\nsystem. The main idea of the method consists in making use of expansions for\nthe Yakubovsky amplitudes onto the basis of the Faddeev components for the\ntwo-cluster sub-Hamiltonian eigenfunctions. The expansions reduce the original\nequations to ones for the functions depending on the relative coordinates\nbetween the clusters. On the basis of the resulting equations the N-(NNN)\nzero-energy scattering problems are solved numerically with the MT I-III model\nfor N-N forces and neglecting the Coulomb interaction between protons.",
