In particular, the original way gauge invariance is taken into account is found to be essential to describe the ratio between the Coulomb and the Transverse cross-sections at large Q2 that has been measured recently at JLab.5 pages, 5 figures, submitted to Phys.Rev.LettHigh Energy Physics - Phenomenologytext
