Configuration space Faddeev continuum calculations. I.n−dscattering length

Formulation of the zero-energy Faddeev-type scattering equations in configuration space is discussed. Numerical solutions are obtained using spline techniques. Scattering lengths are calculated for the $s$-wave $\mathrm{NN}$ interaction models of Malfliet and Tjon; comparison with previously published results and Kohn variational estimates are made. Faddeev amplitudes and Schrödinger wave functions are plotted. Significant features of the configuration space solutions are identified.
