How Does the Finite Size of the Nucleus Affect Hydrogen's Ground State Energy?

[andyfreesty1e]

Homework Statement

calculate the correction to the energy of the ground state of the hydrogen atom due to the finite size of the nucleus treating the nuclear charge as a thin shell of radius r0.

I posted this not that long ago, i know what to do but i just can't figure out what the perturbation is, so any help in finding what the perturbation is will be very very helpful

thanks
