Time-scale of Compton scattering

AI Thread Summary
Compton scattering is debated regarding whether it has a time-scale or is instantaneous, akin to classical elastic collisions. Some suggest that energy transfer can be related to a time duration using the formula δt ≈ ħ/δE, potentially leading to intriguing insights. The discussion also touches on the idea that even instantaneous events might have an infinitesimal duration when considered in terms of Planck time. However, the physics at the Planck scale remains largely unknown, leaving this topic open for further exploration. The conversation highlights the complexities of understanding time in quantum events.

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.

Thread 'A quartet of epi-illumination methods'
Well, it took almost 20 years (!!!), but I finally obtained a set of epi-phase microscope objectives (Zeiss). The principles of epi-phase contrast is nearly identical to transillumination phase contrast, but the phase ring is a 1/8 wave retarder rather than a 1/4 wave retarder (because with epi-illumination, the light passes through the ring twice). This method was popular only for a very short period of time before epi-DIC (differential interference contrast) became widely available. So...
I am currently undertaking a research internship where I am modelling the heating of silicon wafers with a 515 nm femtosecond laser. In order to increase the absorption of the laser into the oxide layer on top of the wafer it was suggested we use gold nanoparticles. I was tasked with modelling the optical properties of a 5nm gold nanoparticle, in particular the absorption cross section, using COMSOL Multiphysics. My model seems to be getting correct values for the absorption coefficient and...
