Description

The tritium target program at Jefferson Lab enabled a range of unique studies of the neutron, allowing for extractions of the neutron magnetic form factor and parton distributions. The comparison of the mirror nuclei 3H and 3He also allows for studies of the isospin structure in multi-nucleon configurations, specifically two- and three-nucleon short-range correlations (SRCs). JLab experiment E12-11-112 was able to isolate scattering from SRCs in 2H, 3H, and 3He, allowing for a detailed study SRC dominance in light nuclei, a comparison of np- and pp-SRCs in the comparison of 3H and 3He, and providing the first constraints on the isospin structure of three-nucleon SRCs.
