Theory of photon and electron induced reactions. Final report, July 1, 1990--June 30, 1993
Theoretical work is reported on the following topics: photo- and electroproduction of mesons by the ({gamma},{pi}{sup {minus}}p) reactions on {sup 12}C and {sup 16}O; Coulomb distortion effects on (e,e{prime}{gamma}) and on inclusive (e,e{prime}) and exclusive (e,e{prime}p) scattering in the quasi-elastic region for {sup 40}Ca, {sup 208}Pb, and {sup 238}U; relativistic structure calculations in which the basic lagrangian is an extension of the {sigma}{endash}{omega} model in which the nucleons are coupled to five fields ({sigma}, {omega}, {rho}, {pi}, the electromagnetic field) and tensor coupling to the vector mesons {rho} and {omega} is also considered; and an investigation of the interaction {gamma} + p {yields} K{sup +} + {Lambda}{sup 0} in a simple quark model that supplies the coupling constants and form factors associated with each vertex in the Feynman diagrams. 19 figs., 51 refs.
