Abstract
We extract the neutron charge form factor GnE(Q2) from the charge form factor of deuteron GdC(Q2) obtained from T20(Q2) data at $0\le Q^2\le$ 1.717 (GeV/c) 2. The extraction is based on the relativistic impulse approximation in the instant form of the relativistic Hamiltonian dynamics. Our results (12 new points) are compatible with existing values of the neutron charge form factor of other authors. We propose a fit for the whole set (36 points) taking into account the data for the slope of the form factor at Q2 = 0.
