The optical theorem states that

$$\left.\frac{d\sigma}{dt}\right|_{t=0}\geq\frac{\sigma_{tot}^{2}}{16\pi}$$ where $\left.\frac{d\sigma}{dt}\right|_{t=0}$ denotes the elastic cross section for unpolarized light beam taken at $t=0$. From the experimental perspective, are there experiments the optical theorem has been verified?
