HIGH ENERGY ELECTRON-SCATTERING AND MODEL INDEPENDENT DESCRIPTION OF CHARGE-DISTRIBUTIONS IN NUCLEI

A method is given to evaluate in a model independent way cross sections for scattering of fast electrons by nuclei. For this purpose the charge distribution in the nucleus will not, as usual, be described by means of the charge density ρ(r), but by the first moment function T(Q): {Mathematical expression} The integration has to be performed over this part of the charge distribution in which the charge will increase from the value 0 to the value Q. Thus T(Q) gives the first moment of this part. It will be shown that this function can be fixed by elastic scattering within certain limits. © 1969 Springer-Verlag.
