The Yakubovsky formalism for the six-nucleon bound-state problem leads to five coupled equations in terms of five independent structures, which can be reduced to two coupled ones, for the case of effective 3-body model, namely -core, and two loosely bound neutrons. In order to calculate the binding energy of the six-nucleon bound system, the reduced coupled Yakubovsky equations are represented in momentum space for a separable nucleon-nucleon interaction. This is the first step toward the calculations of the six-nucleon bound-state problem in the Yakubovsky approach. Comparison of our numerical results for binding energies of six-nucleon and four-nucleon problems with respect to the regarded Yamaguchi separable potential confirms that the six-nucleon bound system, in the case of effective -core structure, is a halo structure.
