Areas of Interest
My research is carried out at Triangle Universities Nuclear Laboratory and at laboratories around the US and overseas. At TUNL, we use polarized beams and polarized targets to test the limits of validity of meson exchange models of the nuclear force and to study parity and time reversal violating symmetry terms in the nucleon-nucleon interaction. Our group has used cryogenic techniques to polarize targets ranging from hydrogen, deuterium and 3-helium up to heavy nuclei such as 165-holmium where we have set some of the tightest bounds on parity even time reversal violation. When the Spallation Source at Oak Ridge comes on-line in 2006 it will be the highest intensity pulsed neutron source in the world. We are working on the design and planning of beam lines for nuclear physics and symmetry studies, focusing particularly on ultracold, cold and epithermal neutrons. We are also collaborating on programs to study the properties of the neutrino, in particular to learn whether they have mass and whether they are their own anti particle. This work is carried out at KamLAND, a US-Japan collaboration now operating a one thousand ton liquid scintillator detector underground in Kamioka, Japan.
