Abstract

The diagonalization of a complex-scaled Hamiltonian is used to calculate the full Green's matrix elements that are valid in the complex energy plane, including the exposed portion of the energy sheet. Three approximate methods are introduced to calculate the partial widths associated with a projectile-target system having several scattering channels. Three potentials are used to check these methods. The results are compared with those obtained by other methods, including the J-matrix method.
