Research Topics:
Structure of exotic nuclei and nuclear states, precision tests of the Standard Model, nuclear reaction dynamics and pre-equilibrium studies.
Present Research Activities:
My research spans a wide variety of areas in low-energy nuclear physics, using multiple techniques at various facilities around the world to perform experiments. My recent and current research activities include: 1) Studies of collective states (those in which many nucleons participate) in nuclei near the valley of stability, and the limits of collectivity in nuclei. The goal of these studies is an understanding how systems of nucleons are organized and how they form collective excitations. 2) Studies of nuclei far from stability exploring the limits of existence, and the consequences of extreme neutron-to-proton ratios. The goal of these studies is to understand the evolution of nuclear collectivity and shell structure as one moves away from the valley of stability and the impact on nucleosynthesis. 3) Precision lifetime and branching-ratio measurements for the super-allowed Fermi beta decays. The aim of these experiments is to obtain a more precise value for the up-down element of the Cabibbo-Kobayashi-Maskawa quark mixing matrix, with the ultimate goal of searching for physics beyond the Standard Model. 4) Studies of nucleon-induced reactions and subsequent gamma-ray transitions with the goal of determining spin distributions in residual nuclei following pre-equilibrium-particle emission. These activities often require travel to facilities such as TRIUMF (Vancouver), Argonne National Laboratory (Chicago, USA), University of Kentucky (Lexington, USA), Los Alamos National Laboratory (Los Alamos, USA), University of Cologne (Cologne, Germany), and the Ludwig-Maximillians University (Munich, Germany). In addition, new detector systems for the TRIUMF facility are in development, concentrating on measuring nuclear lifetimes down to 10 ps. Analysis of the data from these experiments is performed in-house at the University of Guelph.
