A Compton scattering experiment is performed by employing an aluminum target. The incident photons encompass wavelength λ. The scattered photons encompass wavelengths λ' and energies E which depend on the scattering angle θ.
(i) Determine at what angle θ are scattered photons with the smallest energy detected?
(ii) At this similar scattering angle θ, determine the ratio λ'/λ for λ = 9.5 pm?
