The Faddeev-Yakubovsky theory is applied to the system of (/sup 4/He)/sub 4/ interacting pairwise through a realistic He-He potential. The S-wave two-body t matrix is obtained using the unitary pole expansion method, while the S-wave (3+1) and (2+2) subamplitudes are obtained by the Hilbert-Schmidt and the energy-dependent pole expansion (EDPE) methods. The convergences of the latter subamplitudes are tested and the superiority of the EDPE over the Hilbert-Schmidt expansion (HSE) is confirmed. The present results also confirm the results of a previous calculation using the amalgamation of two-body correlations into the multiple-scattering process (ATMS).
