RESONANCES, CROSS-SECTIONS, AND PARTIAL WIDTHS BY THE COMPLEX COORDINATE METHOD

The Complex Coordinate Method (CCM) is reviewed, emphasizing the theoretical aspects and properties of the complex-scaled Hamiltonian. it is shown that the CCM not only enables the calculation of resonance positions and widths by computational techniques that had originally been developed for bound states, but also can be used as a powerful tool in the calculation of scattering cross sections and partial widths.
