How to calculate the energy in gamma photons

AI Thread Summary
To calculate the energy of gamma photons moving in opposite directions from the same origin, one must consider the formula E = hγ, where E is energy, h is Planck's constant, and γ is the Lorentz factor. The discussion emphasizes the importance of having specific data about the photons or the process that generated them, as a formula alone cannot provide answers without input values. Understanding mass invariance in relativity is crucial for accurate calculations. The conversation highlights the need for context and details regarding the photons in question. Accurate energy calculation requires both theoretical knowledge and empirical data.

how do I calculate the energy of to photons moving in the opposite direction. starting from the same origin.
 
Science news on Phys.org
E = hγ ?
 
I mean using just the mass invarians of relativity

If you have no data to use as input, a formula will not help. What do you know about these photons or about the process that produced them?
 
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...
