第三題
High energy Gama rays are scattered from electrons initially at rest. Assume
the photons are backscattered and their energies are much larger than the
electron's rest-mass energy, E>>mc2
(a)calculate the wavelength shift？
(b)Show that the energy of the scattered photons is half the rest mass
energy of the electron, regardless of the energy of the incident photons.
(c)Calculate the electron's recoil kinetic energy if the energy of the
incident photons is 150Mev?
