Sachs form factors

The Zemach correction was calculated numerically in a number of papers, see, e.g., [5, 6, 7], The most straightforward approach is to use the phenomenological dipole fit for the Sachs form factors of the proton... 

However, this is not yet the end of the story, since the proton charge radius is usually defined via the Sachs electric form factor Gp, rather than the Dirac form factor Fi... 

The Sachs electric and magnetic form factors are defined as (see, e.g. [3])... 

We will first consider the contributions generated only by the elastic intermediate nuclear states. This means that calculating this correction we will treat the nucleus as a particle which interacts with the photons via its nontrivial Sachs electric and magnetic form factors in (6.8).
