Just want to make sure if I have this correct and to ask a question,

If you pass an electric field through an atom, it polarizes it the atom with a dipole moment p = \alpha E where is a constant of polarizability and E the electric field. Because of the electric field, the nucleus moves in the direction of the field, and the electron cloud shifts the other way. So the nucleus shifts a distance d from the cloud. Because the electric field exerts a force on the nucleus, the electron cloud exerts a force based on d (from the centre) until the two reach equilibrium.

My question is where you should start to find the exact value of d for which equilibrium is reached, the dipole moment at this point, and lastly determine the polarizability constant in terms of the volume
