Description

A Faddeev equation for a radial part the Faddeev component of a three-particle wave function was solved in order to determine the length of scattering of a particle on a bound pair. The method of solution is based on finite-dimensional approximation of the Laplacian by a linear combination of projection operators. For the potential averages over the hyperspherical angle the scattering length was found to be 3.59 F within the 4-rank approximation
