It is proposed to study radiative level shifts in hydrogen,                spectra and decays of bound quark-antiquark systems, and                        radiative corrections to toponium decay.  The major effort                      concerns the lamb shift of hydrogen.  The work entails                          calculation of pure recoil corrections resulting from triple                    Coulomb exchange, as well as single Coulomb exchange.  A                        calculation of two loop radiative graphs, using Dirac Coulomb                   propagators, will be initiated.  Proposed work on quarkonium                    bound states will be directed toward formulating a coupled                      channel mixing approach in which the virtual states are treated                 relativistically.  Research on toponium decay will involve                      analysis of virtual Higgs contributions.
