X-rays with energy 51.1 keV produced incoherent scattering by
impacting with an electron in the outershell of an atom in a sample. Answer
to the following questions.
(1) Estimate the angle (so-called recoil angle ) between the direction of the
recoil electron and that of the incident X-ray beam, when the scattering
angle 2 is 20ı.
(2) Compute the energy of the scattered photon in this case.

X-rays are produced when the electron stream in an x-ray tube knocks an electron out of a low-lying shell of an atom in the target, and an electron from a higher shell falls into the lower-lying shell. The x-ray is the photon given off as the electron falls into the lower shell. The most intense x-rays produced with a copper target have wavelenghts of 1.542A and 1.392A. These x-rays are produced when an electron from the L or M shell...
