WebThe word "stimulated" means that the emission of the photon is "encouraged" by the existence of photons in the same state as the state where the new photon may be added. The "same state" is one that has the same frequency, the same polarization, and the same direction of motion. WebPhysics questions and answers. The conservation of energy and momentum equations for Compton scattering can be used to find a solution that eliminates the electron from the equations and relates the outgoing photon at an angle 0 to the incoming photon. = mc h 1-1= (1 - cos 0) Case A: At what angle does the outgoing photon have the smallest ...

An incoming photon in this stream collides with a valence electron in the graphite target. In the course of this collision, the incoming photon transfers some part of its energy and momentum to the target electron and leaves the scene as a scattered photon. WebAug 31, 2024 · To be detected, the photon must make its path throughout the passivation layer on top of the silicon surface before it reaches the multiplication region of interest and triggers the breakdown. Hence, we broke down the photon detection into two phases: the photon transmission and the avalanche triggering. cia opium cultivation in afghanistan

"WebMar 29, 2024 · The photomultiplier is an instrument that can detect photons. An incoming photon (e.g. a scintillation photon) hits the photo-cathode and via photo effect releases an electron. The probability for this process is about 20%, so you need on the average 5 photons to produce a single photo-electron. " - Incoming photon
