  Some results obtained by a new method for solving the Bethe-Salpeter equation
are presented. The method is valid for any kernel given by irreducible Feynman
graphs. The Bethe-Salpeter amplitude, both in Minkowski and in Euclidean
spaces, and the binding energy for ladder + cross-ladder kernel are found. We
calculate also the corresponding electromagnetic form factor.
