Nucleon structure study using a polarized $^3$He target

Due to the unique ground state spin structure of the $^3$He nucleus, polarized $^3$He nuclear targets have been used widely in experiments ranging from measurements of the neutron electric and magnetic form factors to the study of the neutron spin structure. In this talk, I will highlight some of the recent results and also discuss upcoming experiments. Particularly, I will discuss the upcoming neutron transversity experiment in Hall A at Jefferson Lab using a vertically polarized $^3$He target and the planned polarized Compton scattering experiment from a polarized $^3$He target at the HI$\gamma$S facility located at the Duke Free Electron Laser Laboratory using the circularly polarized photons. All these experiments benefit greatly from theoretical developments in calculating the three-body system. The work is supported in part by a U.S. Department of Energy grant DE-FG02-03ER41231.
