Title:     Scattering problems using the Hyperspherical Adiabatic Expansion Method.

Abstract: When studying nuclear reactions, using the Adiabatic Expansion Method
has the great advantage of giving a clear distinction between all the
possible outgoing channels. The phase shift of a scattering process is
easily obtained from the long distance wave function. Nevertheless, it
is well known that calculating the wave functions at long distances
implies needing to calculate accurately enough, up to very long
distances, a large amount of adiabatic potentials. This makes the
calculation very delicate and computationally very expensive.

In this work we solve these technical difficulties using two integral
relations derived from the Kohn Variational principle, since the phase
shift information is also contained, this time in a more subtle way, in
the short distance part of the wave function.
