- Consider an electric dipole consisting of two electric charges e and −e at a mutual distance 2a.

Consider also a particle of charge e and mass m with an incident wave vector k perpendicular to

the direction of the dipole.

1. Calculate the scattering amplitude in the Born approximation. Find the directions at which

the differential cross section is maximal.
