Interpretation of recent form factor data in terms of an advanced representation of baryons in space and time

NUCLEAR STRUCTURE ¹H, NN; analyzed available data on electromagnetic form factors of proton, neutron, and Λ from annihilation and scattering reactions; deduced neutron-proton effective form factor correlation, neutron-proton and Λ-proton correlation, Time-like effective form factor of the nucleon as a function of the relative momentum. Data interpreted in the frame of a generalized picture of the internal structure of baryons.
