摘要：

It is demonstrated a coincidence of the proton electric rms radius from the global analysis of the JLab proton polarization data together with all other existing nucleon electromagnetic form factor data in the framework of the Unitary& Analytic model of nucleon electromagnetic structure with its value recently determined in a spectroscopy of muon hydrogen atom. The result confirms a non-dipole behavior of the proton electric form factor in the space-like region and strengthen a belief in an existence of the proton electric form factor zero revealed in global analysis of nucleon form factors data.
