| Publication Abstract: | We report the first measurement of the (e,e'p) reaction cross-section ratio for Helium-3 (3He) relative to Tritium (3H). The measurement covered a missing momentum range of 40 < pmiss < 550 MeV/c, at large momentum transfer (Q2 = 1.9 (GeV/c)2 ) and xB > 1, which minimized contributions from non quasi-elastic (QE) reaction mechanisms. The data is compared with calculations performed within the plane-wave impulse approximation (PWIA) using realistic spectral functions and momentum distributions. The measured and PWIA cross-section ratios agree within the measurement accuracy of about 3% up to the nuclear Fermi-momentum (~ 250 MeV/c) and differ by 20% to 50% at higher momenta. Final state interaction (FSI) calculations using the general- ized Eikonal Approximation indicate that FSI should change the 3He/3H cross-section ratio for this measurement by less than 5%. This suggests that the differences at large missing momenta between the 3He/3H experimental and calculated ratios could be due to the underlying NN interaction, and thus could provide new constraints on the previously loosely-constrained short-distance parts of the NN interaction. | ||
