In this case a new xgrid is defined for the continuum states and the
wave function in xgrid values with high values of the potential are set
to zero to avoid numerical errors. Done for one of the cases. Needs to be checked and extended to the other case.

Check the convergence criterium. Recomputed avoiding the states normalization.
