WebSep 13, 2015 · Photon-photon scattering does not occur in any currently obtainable conditions, and electron-electron scattering, so far, has not revealed a finite radius. Bottom line: particle size depends on the definition of size, which boils down to measurement method. I personally am comfortable with saying that a photon's size is the size of its ... WebJul 31, 2024 · Another channel for free electron generation is interband excitation, for which the two-step excitation model through the intermediate state has been proposed . For this excitation, the photon energy of 3.49–4.66 eV is required for each step, indicating four photons in total for the 532 nm beam. We have found m = 3 photon process for VIS pulses

First, note that the formulae given by the OP do not in themselves exclude the possibility that the electron has the same or greater energy than a photon of the same wavelength. Webtwo-photon uncaging at 900 nm versus 720 nm. This new caging chromophore, called DEAC450, has an extended π-electron moiety at the 3-position that shifts the absorption spectrum maximum of DEAC from 375 to 450 nm. Two-photon excitation at 900 nm was more than 60-fold greater than at 720 nm. Two-photon uncaging of DEAC450-Glu Webphoton 0 eV/c2 0 0 0 1) MeV = mega-electron-volt = 106 eV. It is customary in particle physics to measure the mass of a particle in terms of how much energy it would represent if it were converted via E = mc2. So, the units for mass become E / c2, or in this case, MeV/c2. 2) e = the charge on the electron, or 1.602 x 10-19 coulomb dialogical relationship
