# Time-scale of Compton scattering

Hey all,
Anyone know if there is a δt to Compton scattering or is it an instantaneous event, entertaining classical physics....billiard balls colliding in an elastic collision.

Cheers

That depends on your interpretation. Relating the transferred energy to a time via $\delta t \approx \frac{\hbar}{\delta E}$ might give some interesting results.

Interesting. Not to go out there too much but that does beg the notion that every event (even instantaneous ones) can be given some infinitesimal duration relative to Planck time.

We don't know how physics at the planck scale looks like.

Not challenging that notion.
