| Zusammenfassung: | Заглавие с титульного экрана The Alt-Grassberger-Sandhas equations for the five-body problem are solved for the case of the driving two-body potentials limited to s-waves. The separable pole expansion method is employed to convert the equations into the effective quasi-two-body form. Numerical results are presented for five identical bosons. Accuracy of the separable expansion is investigated. It is shown that both in (1+4) and (2+3) fragmentation, the corresponding eigenvalues decrease rather rapidly, what, combined with the alternation of their signs, leads to rather good convergence of the results. |
