Research Interests
Since 1990 I have collaborated with physicists at Triangle Universities National Laboratory (TUNL) on the campus of Duke University. Dr. Mark Spraker of NGCSU is also part of this collaboration. Our primary activities have been studying nuclear reactions at very low energies (£ 160 keV). Reactions at these low energies are simpler to analyze and also are of interest in nuclear astrophysics. In particular, we study reactions induced by polarized proton or deuteron beams. Most of the studies have concentrated on radiative capture reactions in which gamma rays are produced. More recently, we have also studied reactions in which neutrons are produced.
In the past several years I have become increasingly involved with experiments at the High Intensity Gamma-ray Source (HIgS), located adjacent to TUNL at Duke University. HIgS is a unique facility that produces beams of nearly monoenergetic, polarized gamma rays that are tunable in energy from 2 MeV to over 150 MeV (when the current upgrade is completed). Experiments so far at the facility include the breakup of 2H and 3He by gamma rays, Compton scattering of gamma rays from 16O, parity determination by nuclear resonance fluorescence and development the experimental facilities.
Several students from NGCSU have gone to TUNL and worked on experiments there. Several of them have subsequently made presentations of their research at national meetings of the American Physical Society. There are currently several NGCSU physics graduates studying nuclear physics in graduate school at Duke University, the University of North Carolina, Chapel Hill, and Florida State University.
Since 1994 the U.S. Department of Energy has supported my research.
