 | Radiative corrections in parity violating electron scattering [Blunden] Next-to-Leading-Order (NLO) effects in the physics of the electro-weak interactions play a crucial role in tests of the Standard Model. Calculations of the NLO contribution are based on the loop corrections. We have calculated the NLO effects in parity-violating electron scattering, with monopole form factors for the hadronic currents, and have computed radiative corrections along with the weak charges of the proton and neutron, and (more recently) one of the larger corrections to the weak charge of the proton, due to the gamma-Z box term.

 | Coupled-channel theory for light-ion reactions [Svenne] A Multi-Channel Algebraic Scattering (MCAS) method of coupled channels is used to obtain detailed information about the scattering of nucleons, or light ions of mass-3 and mass-4, on light and medium-mass nuclei. The predictive power of MCAS is applied to unstable systems, nuclei at and beyond the drip lines; it provide reliable information on radiative capture (fusion) processes at very low energies for nuclear systems important to stellar evolution and nucleosynthesis.
