electron and is red-shifted by 2.426 pm, and the recoil electron gains a speed of 0.6c. Here c is the speed of light in vacuum. (a) Determine the scattering angle of the photon (in degree).

(b) Calculate the kinetic energy (in keV) and the linear momentum (in kg?m/s of the recoil electron.

(c) Find the angle (in degree) between the travelling directions of the scattered photon and the recoil electron.

(d) Determine the wavelength (in pm and the energy (in keV) of the photon before and after scattering.

Express the values to 3 significant figures, if necessary.

C3. Refer to the figure below, in a Compton scattering experiment, a photon hits a stationary, free electron and is red-shifted by 2.426 pm, and the recoil electron gains a speed of 0.6c. Here c is the speed of light in vacuum. (a) Determine the scattering angle of the photon (in degree). (2 marks) (b) Calculate the kinetic energy (in ke V) and the linear momentum (in kg.m/s) of the recoil electron. (2 marks) (c) Find the angle (in degree) between the travelling directions of the scattered photon and the recoil electron. (4 marks) (d) Determine the wavelength (in pm) and the energy (in keV) of the photon before and after scattering. (2 marks) Express the values to 3 significant figures, if necessary.
