ResSearch
This comand searches for poles in the S matrix for scattering from the local potential in the piece-wise diabatic form obtained from the command GetDPot. The input defines a grid of energies in the complex plane. The S^(-1) matrix is then computed at each energy. Using polynomial interpolation, the approximate location of the zeros are located. Finally, the poles the S matrix are located using the approximate locations as initial guesses. The resonant energies are written to file fort.83.
