Now, Fermi’s Golden Rule gives the rate for electron transfer across the barrier, and is written
::<math> w = \frac{2 \pi}{\hbar} |M|^2 \delta (E_{\psi} - E_{\chi}
where δ(Eψ-Eχ) restricts tunneling to occur only between electron levels with the same energy<ref name="Chen"/>. The tunnel matrix element, given by
::<math> M= \frac{\hbar}{2 \pi} \int_{z=z_0} (
is a description of the lower energy associated with the interaction of wave functions at the overlap, also called the resonance energy<ref name="Chen"/>.
