Hello,(adsbygoogle = window.adsbygoogle || []).push({});

The problem I have is trying to derive a formula for the compton equation, but instead of having the electron at rest, it is moving in the same direction as the incident photon. I've tried deriving it in the same manner as deriving it for an electron at rest (ie. I've simply made the change that the initial momentum and energy of the electron is no longer 0, with electron initial and final energies being of the form E=sqrt(m^2c^4 + p^2c^2)), but it seems to me that doing so results in too many extra terms that don't cancel out.

Is there something I'm missing here?

Thanks,

W. =)
