1) Write down Rutherford, Mott and
Rosenbluth formulas describing  electron-proton scattering.
Explain the differences and how they relate to the cases
each of them is applicable to?

2) In case of electron-proton elastic scattering, with finite
size proton described by Rosenbluth formula: could you explain
what are the components of the formula.
Explain what are the form-factors.

3) How is described differential cross-section for inelastics
scattering e p->e X. What are the characteristic kinematical
variables. 

4) What you can say about parton distribution functions
and quark parton model.
