Scattering Theory (cont.)
Born approximation
Gives a differential cross section
which can be experimentally determined
Finite Radius Approximation
Densities can be approximated by zero far from the particle
Density is the Fourier transform of the form factor → F is band limited
Can use the sampling theorem
