Research Categories: Experimental Nuclear Physics

Current projects: Measurement of the cross section for neutron-neutron quasi-free scattering , in neutron deuteron break; Determination of the s-wave neutron-neutron, scattering length using photodisintegration of the triton; Nuclear structure, studies of nuclei used in the search for neutrinoless double beta decay;, Nuclear reaction measurements important for nuclear security and , homeland security; and Carbon and nitrogen accumulation , and translocation in plants.

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 3He and the triton, 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
nuclear structure
ecology and plant physiology
material analysis and imaging with gamma-rays and neutrons

Curriculum Vitae

Highlight:

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.
