Abstract

A new value b=0.0205±0.0017 fm² of the slope of the neutron form factor G_En(q²) at q²=0 compatible with deuteron properties has been extracted by using a linear relation between b and A²_S(1+η²) we found for a class of nonlocal potential models having the experimental values of both r_D and Q. Another \it model dependent value b^{\rm MHKZ}=0.0206±0.0014 fm², which is also compatible with deuteron properties, has been determined by applying "constrained" unitary transformations to the local MHKZ potential model. The sensitivity of a small changes in the experimental values used for r_D and Q on the value obtained for b is also investigated.
