Regular ArticleRelationship between Feshbach's and Green's Function Theories of the Nucleon–Nucleus Mean Field☆
We clarify the relationship and difference between theories of the optical-model potential which had previously been developed in the framework of Feshbach's projection operator approach to nuclearExpand

Projection Operator Approach to the Self-Energy
Abstract Feshbach's projection operator formalism is extended to the description of the self-energy. This necessitates the introduction of "extended'' projection operators. They act within anExpand

Orthogonality and the Perey factor in knockout reactions induced by electromagnetic probes
Abstract We discuss the problem of the lack of orthogonality between continuum final states obtained by the use of an optical potential and the initial bound states in the description of knockoutExpand

Projection-operator approach and final-state interaction in electromagnetic nuclear reactions
Abstract The final-state interaction in exclusive and inclusive reactions is investigated by Feshbach's method of projection onto P - and Q -spaces. From an exact treatment of the Q -space effects,Expand

Antisymmetrized Green’s function approach to (e, e′) reactions with a realistic nuclear density
A completely antisymmetrized Green’s function approach to the inclusive quasielastic (e, e′) scattering, including a realistic one-body density, is presented. The single-particle Green’s function isExpand

Resonance conditions for the spectral function and single-hole states in finite nuclei
Abstract An equation for the spectroscopic amplitudes in finite nuclei is determined both in the discrete and in the continuous spectrum of the residual nucleus hamiltonian. Its structure, involvingExpand

Equivalent potentials in the description of scattering processes
Some connections among nonlocal, almost local and local descriptions of scattering processes are investigated. An extension of the Perey-Saxon expansion for the Frahn-Lemmer model gives formally anExpand
