A scattering of light particles from a heavy stationary particles, . .

  1. Dec 10, 2006 #1
    A scattering of light particles from a heavy stationary particles, the momentum of the light particles change direction after scattering, and we could use Born approximations.
    We also take that the initial momentum and the final momentum has the same magnitude.
    But how could it be when total momentum should be conserved?

    Can you justify your claim ?

    For M>>k, the neglect of recoil is a reasonable approximation.
    For smaller M, the recoil momentum has to be included, and you have the
    Compton effect with a change in wavelength.
