Query: Complex scaling method for three- and four-body scattering above the
  break-up thresholds   A formalism based on the complex-scaling method is presented to solve the few
particle scattering problem in configuration space using bound state techniques
with trivial boundary conditions. Several applications to A=3,4 systems are
presented to demonstrate the efficiency of the method in computing elastic as
well as break-up reactions with Hamiltonians including both short and
long-range interaction.
