Its application to a specific eight-resonance unitary and analytic model of nucleon electromagnetic structure, describing also the time-like nucleon electromagnetic form factor data, explains the positive central values from recent SAMPLE and HAPPEX experiments.4 pages, 2 EPS figures, RevTeXHigh Energy Physics - PhenomenologyNuclear Theorytext
