Werner Sandhas
Werner Sandhas from the University of Bonn was awarded the status of Fellow in the American Physical Society, after he was nominated by their Topical Group on Few-Body Systems in 1990, for development of fundamental theoretical methods for the exact treatment of few-nucleon problems, including the development of methods for 3-, 4-, and n-particle scattering theory and methods for the inclusion of coulomb effects in the 3-particle problem.
