摘　　要：We report the density measurement through e-3He elastic scattering with a 1.23 GeV electron beam in Jefferson Lab experiment E06-010. The extracted 3He density is （9.26±0.06） amagats and the N2/3He ratio is （1.49±0.08）%. In addition, these results are consistent with the deduced target densities based on pressure broadening measurement.We report the density measurement through e-3He elastic scattering with a 1.23 GeV electron beam in Jefferson Lab experiment E06-010.
