Nuclear physics is the study of nuclear matter in its many states and the interactions of other nucleons and sub-atomic particles with them. This ranges from low-energy searches for dark matter and neutrino physics to high energy electron scattering off of nuclear targets. The Duke physics department is the host of the Triangle Universities Nuclear Laboratory (TUNL) at which researches from Duke, the University of North Carolina at Chapel Hill, and North Carolina State University work together. TUNL hosts several accelerators for nuclear astrophysics and a high intensity gamma-ray source which utilizes the Duke free electron laser. Duke researchers also work at JLAB in Virginia and Los Alamos Laboratory in New Mexico. See all Nuclear Physics information.
