Research Program

Our research program centers on photon induced reactions. The measurements proposed are all designed to test fundamental concepts and assumptions in subatomic physics. These include: testing current models of the nucleon-nucleon interaction through photodisintegration of light nuclei, looking for new physics through direct measurement of the Gerasimov-Drell-Hearn sum rule for the Deuteron, testing the model of the deuteron through measurement of the neutron polarization following low-energy photodisintegration of the deuteron, and testing QED predictions of the gamma ray pair-production asymmetry.

Our work is carried out primarily at the High Intensity Gamma Source (HIGS) at the Duke University Free-Electron Laser Facility (DFELL).

Our group is part of multi-university collaborations from Canada, USA, Sweden, Ukraine, and Israel.

Some more details of our program are given in this brief.
