Could you provide a link to said derivation? You keep talking about a constant potential, but what you describe is in fact a time-dependend potential.

It means that after waiting a reasonably large time after the transition the final state has the same energy as the initial state. Due to the perturbation term in your Hamiltonian your final state is a mixture of many energy eigenstates with energy peaked around the value of the initial state...

I'm fully aware that this post is over one year old, but could someone provide a source for the above statement or at least scetch if and why this is true?
