Boundary One-Point Functions, Scattering Theory and Vacuum Solutions in   Integrable Systems
  Integrable boundary Toda theories are considered. We use boundary one-point functions and boundary scattering theory to construct the explicit solutions corresponding to classical vacuum configurations. The boundary ground state energies are conjectured.
