RDWIA analysis of 12C(e,e'p) for Q² < 2 (GeV/c)²

Original · EN

We analyze data for 12C(e,e'p) with Q² < 2 (GeV/c)² using the relativistic distorted-wave impulse approximation (RDWIA) based upon Dirac-Hartree wave functions. The 1p normalization extracted from data for Q² > 0.6 (GeV/c)² is approximately 0.87, independent of Q², which is consistent with the predicted depletion by short-range correlations. The total 1p and 1s strength for Eₘ < 80 MeV approaches 100% of IPSM, consistent with a continuum contribution for 30 < Eₘ < 80 MeV of about 12% of IPSM. Similarly, a scale factor of 1.12 brings RDWIA calculations into good agreement with 12C(e,e'p) data for transparency. We also analyzed low Q² data from which a recent NDWIA analysis suggested that spectroscopic factors might depend strongly upon the resolution of the probe. We find that momentum distributions for their empirical Woods-Saxon wave functions fit to low Q² data for parallel kinematics are too narrow to reproduce data for quasiperpendicular kinematics, especially for larger Q², and are partly responsible for reducing fitted normalization factors.
