Configuration-space Faddeev calculations for bound states of three identical particles using the tensor method

The three-body problem is solved at negative energies using the Faddeev-Noyes equations. The latter are reduced to a matrix equation by spline approximation and orthogonal collocation. This matrix equation is solved using a method that is based on the tensor structure of the matrices. High-accuracy results obtained with this method for systems of three identical particles are presented, for various values of the total angular momentum and for various potential strengths and shapes.Dedicated to Profs.
