Query: Solutions of Faddeev-Yakubovsky equations in configuration space for the
  4N scattering states   The Faddeev-Yakubovsky equations in configuration space have been solved for
the four nucleon system with special interest in their scattering states. We
present results concerning the structure of the first $^4$He, scattering states
in different (T,S) channels including the first inelatic threshold
N+3N$\to$NN+NN and the n-t cross section using realistic potentials.
