- Homework Statement
- An accelerator produces an electron beam with energy E=20 GeV. The electrons diffused at θ=6° are detected. Neglecting their recoil motion, what is the minimum structure in the proton that can be resolved?
- Relevant Equations
- De Broglie wavelength, λ=h/p and particle energy in natural units $$E =\sqrt{m^2 + p^2} $$
Hi all. I'd personally consider the De Broglie wavelength λ=h/p, with p being the momentum of the electron beam. I get $$\lambda \simeq 0.6 \times 10^{-18} m $$ and since the radius of a quark is ## \leq 10^{-19} m ##, the proton structure can't be resolved. I'm quite sure there's something wrong with my reasoning, since I didn't use the information on θ.
