Few-body Studies at TUNL/HIGS

An overview of experiments designed to understand the dynamics of few-body nuclear systems (A=2-4) at the Triangle Universities Nuclear Laboratory (TUNL) and the High Intensity $\gamma$-Ray Source (HI$\gamma$S) will be presented. A review of global experimental data and key advances in theory will be discussed. The talk will focus on the work at HI$\gamma$S on photodisintegration of the deuteron and $^3$He with polarized gamma-rays and measurements of angular distributions of cross sections and analyzing powers as well as total cross sections. Plans for measurements of cross sections of the photodisintegration of $^4$He will be presented. In addition, a brief description of few-body experiments at TUNL will be given, outlining nucleon-deuteron and nucleon-$^3$He scattering experiments. The impact of these measurements on potential-model and effective field theory calculations of 2-, 3-, and 4-body systems will be presented.
