Abstract
We show that the "boundary crossingunitarity equation" recently proposed by Ghoshal and Zamolodchikov is a consequence of the boundary bootstrap equation for the Smatrix and the wallbootstrap equation. We solve this set of equations for all affine Toda theories related to simply laced Lie algebras, obtaining explicit formulas for the Wmatrix which encodes the scattering of a particle with the boundary in the ground state. For each theory there are two solutions to these equations, related by CDDambiguities, each giving rise to different kind of physics.
