The isospin structure of the 3-nucleon form factors
The IS-IV separation of the 3-nucleon elastic form factors has required a careful re-analysis of the existing experimental data, followed by the functional representation (SOG) of their q2 behavior. A first result has been the extraction of a “consistent” set of experimental values for the RMS radii. The IS-IV separation itself Yields very clear conclusions for the magnetic part : evidence for a good control over the one-body operators and for the IV MEC calculations is found. For the charge form factors the possible conclusions about the disagreement between theory and experiment are dominated by the still open and puzzling PS-PV problem : further theoretical constraints on the MEC in charge form factors are required.
