Question

A photon with energy of 55keV is incident upon a freeelectron. The scattered photon is detected at an angle of 60 degrees with respect to theincident photon. a) What is the wavelength of the scattered x-ray photon? b) What is the magnitude of the recoiling electron’skinetic energy? c) Use conservation of momentum to determine the angle atwhich the recoiling electrons are detected.

Explanation / Answer

given scattered photon energy = 55kev scattred photon angle = = 600 E = hc/ = hc/E plug values to get wavelength of scattered photon = 1 = +h/mc (1-cos) where h/mc = 2.43 *10-12 m kinetic energy = p2/2m , where p = h/,and m is mass of electron plug values E = hc/ = hc/E plug values to get wavelength of scattered photon = 1 = +h/mc (1-cos) where h/mc = 2.43 *10-12 m kinetic energy = p2/2m , where p = h/,and m is mass of electron plug values
