Experimental nuclear physics

Doctor of Philosophy, Duke University, 1984
Master of Art, Duke University, 1980
Bachelor of Science, Davidson College, 1978

Research Categories: Experimental Nuclear Physics

Current projects: Study of the Star Anomaly in neutron-deuteron breakup, Measurement of the neutron-neutron scattering length, Carbon and nitrogen accumulation and translocation in plants, Element imaging in materials, Explosive nucleosynthesis

Research Description:

Professor Howell is the Director of the Triangle Universities Nuclear Laboratory (TUNL). His research interests are the quantum chromodynamics (QCD) description of structure and reactions of few-nucleon systems, Big Bang and explosive nucleosynthesis, and applications of nuclear physics in biology, medicine and national security. His research includes: studies of few-nucleon reaction dynamics, measurements of the neutron-neutron scattering length, photodisintegration of the deuteron and beryllium at energies relevant to astrophysics processes, and studies of the carbon and nitrogen accumulation and translocation in plants using short-lived radioactive isotopes and positron emission tomography.

Areas of Interest:
experimental nuclear physics
few-nucleon reactions
nuclear astrophysics
ecology and plant physiology
material analysis and imaging with gamma-rays and neutrons
