Assume That the Equation E_{photon, F} = (E_{photon, I})/[ 1

Assume that the equation E_{photon, f} = (E_{photon, i}) /[ 1 + (E_{photon, i}/m_ec²) (1 - cosè) ] can be applied to all scattering angles è. When Compton scattering occurs, what is the E_{photon, i} scattering angle when the final energy of a scattered photon differs the most from the photon's initial energy?

A) 0°
B) 90°
C) 180°
D) 270°
