Inclusive Short-range Correlation Measurement with 3H and 3He at Jefferson Lab

The nucleon-nucleon potential has a strong repulsive core. When a two-nucleon (sub)system falls into this range, they will interact strongly and move away from each other with large momentum. In electron Quasi-elastic(QE) scattering, these so-called short-range correlation(SRC) pairs in nuclei produce events with nucleon initial momentum above the Fermi level.
Previous experiments reported a neutron-proton pair (isosinglet) dominance in high-momentum nucleons. This n-p dominance is believed to cause a scaling behavior of nuclei inclusive cross section ratios at 1.4<xbj<2 where the hign-momentum nucleons dominate. At Jefferson Lab Hall A we check this np-dominance of SRC via the electron scattering on A=3 nuclei system. In the past year we measured the 3H to 3He cross section at 1<x < 3 with a wide Q2 range (0.4<Q2< 3 GeV2). In this talk I will show the status of 3H/3He ratio analysis at 1<xbj<2 with Q2=1.4GeV2 and 1.8GeV2 data.
