Compton corresponds ... The new type of light scattering discovered by us naturally requires very powerful illumination for its observation. In our experiments, a beam of sunlight was converged ...

"In our experiments, we showed that the momentum ... associated only with high-energy—gamma—photons in classical Compton scattering. Ultimately, our research paves the way to broaden ...

In this formula, unfortunately, no account was taken of the change of frequency of the radiation during the first scattering. When this mistake, which has been kindly pointed out to me by Mr. Chr.
