Resumo

For pt.I see Huby, Nucl. Phys., vol.A167, p.271 (1971). A theory is developed for resonant nucleon-nucleus scattering which yields a particularly apt form of wavefunction for use in calculating DWBA matrix elements for stripping to unbound levels. It is a generalization of an existing theory to cover the case that the unbound state can decay through more than one channel. A concise matrix formulation is employed to deal with the greater complexity of the model. The end product is to put a known prescription for the stripping form factor and spectroscopic factor on a sound theoretical basis.
