Partial-wave decomposition of the Faddeev amplitude of a   Poincar\'e-invariant three-fermion bound state
  A partial-wave decomposition of the Faddeev amplitude of a Poincare-invariant three-fermion bound state is presented. Some implications for the properties of the nucleon as relativistic three-quark bound state are discussed. E.g. it is demonstrated that the nucleon is not spherically symmetric.
