Abstract:
The finite range expansion method
[Y. Koike, Prog. Theor. Phys. 87 (1992), 775],
which gives well converged solutions of the three-body Faddeev equations,
is extended to the three-body and two-two subsystems
in order to solve the four-body Faddeev-Yakubovsky equations.
A feasibility study is carried out to check the convergence
in a four-nucleon system at 3.45 MeV below the four-body break-up threshold,
which is in between the 2N-2N and 2N-N-N break-up thresholds.
We obtain a converged phase shift and inelasticity parameter
to 6 digits for 3N+N elastic scattering.
