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

I'm working on a problem about neutrino-electron scattering $$\overline\nu_ee^-\to e^-\overline\nu_e.$$ The problem says to prove that the maximum angle of emission for the recoil electron relative to the neutrino beam is $$\sqrt{{2m\over E}},$$ but I have worked on this for hours and I don't understand how to proceed. The problem doesn't say that this is an elastic scattering case, but I've been assuming so...any suggestions?

Btw, m and E are the electron mass and energy in the formula for the maximum angle.

Thanks
