Momentum vectors during a 90-degree Compton scattering event.
Momentum vectors during a 90-degree Compton scattering event.
A photon with initial wavelength \(\lambda_0\) collides with an electron that is initially at rest. The photon scatters at an angle of \(90^\circ\) relative to its initial direction of motion, emerging with a longer wavelength \(\lambda'\). Which of the following expressions represents the de Broglie wavelength \(\lambda_e\) of the recoiling electron immediately after the collision?
