Graduate Can scattering experiment be used to determine location and momentum of an electron?

[sumitgarg1]

It seems Compton scattering experiment can be used to determine location of electron by hitting it with photon.
As per Compton scattering. if we measure λ' , λ and θ accurately; the location of electron can be determined.(in theory).

λ' - λ = h(1-cosθ)/m*c

also when θ=π then :

Δp = h*/λ -h*/λ'

Δx = c * Δ t / 2 where Δ t = time interval of photon discharge from source and receiving it on detector.

In this scenario ; can someone please explain how uncertainty principle applies to Compton scattering??

This is already being discussed in your post on Physics Stack Exchange:

I haven't read the Stack Exchange thread, but at a heuristic level, looking at your expressions for $\Delta p$ and $\Delta x$, the former involves wavelength and the latter involves time. Those are complementary observables just as momentum and position are complementary observables. So you haven't found a way to avoid the uncertainty principle; you've just exchanged one pair of complementary observables for another.
