Hi all
Can someone please describe how the form factor used in Rutherford scattering is applicable to neutron probing of nuclei? Also, is the kinetic energy required to probe a given radius simply given by the de Broglie wavelength where momentum, p >= hbar / Radius ? (Relativity neglected) Thanks

For nuclear scattering for neutrons there is no form factor, because the nucleus is so tiny.
Xray and magnetic neutron scattering probe the electrons which are quite extended. The form factor is basically the Fourier transform of the electron density around the nucleus. The FT of a delta distribution is constant, hence no form factor for nuclear scattering. Kinetic energy is p^2/2m
