Can photons combine
WebJun 29, 2016 · $\begingroup$ The tensor meson f'(1525) with spin 2 has a 2γ decay mode, so the two photons also combine symmetrically to J=2. By Yang's theorem/symmetry, they cannot combine to J=1, so no vector meson decays to 2 photons. $\endgroup$ – WebWhen a photon is absorbed by chlorophyll, the energy level of some of the electrons in the pigment is raised. Which of these are possible after that? The energy can be released as heat. The pigment can fluoresce or phosphoresce. The absorbed energy can eventually be stored in chemical bonds.

WebApr 6, 2024 · The electrons (and positrons) have 1/2 spin, thus they can annihillate in +1/2, -1/2 or in +1/2, +1/2 configuration. Thus, their summed spin is either 0 or 1. The spin of the photons is 1, also they can opposite or equal sign, … WebSep 6, 2024 · The reason photons can collide and produce W bosons in the LHC is that at the highest energies, those forces combine to make the electroweak force. ... Having photons ‘merge’ into some interesting mass/energy bit due to what we can call a collision was concurrent with getting the protons up to near light speed and collision type proximity ...
WebIn the anhiliation process you have two vertices with photons. It means there is a virtual electron/positron involved in the process. So I suppose in some sense, you can have spontanious pair production but it requires the electron-positron pair produced are virtual, and hence short lived. – user3728501 Jun 18, 2024 at 12:10 Web1.

If either the electron or positron, or both, have appreciable kinetic energies, other heavier particles can also be produced (such as D mesons or B mesons), since there is enough kinetic energy in the relative velocities to provide the rest energies of those particles. Alternatively, it is possible to produce photons and other light particles, but they will emerge with higher kinetic energies. fly tipping bwdWebMerge as many images as you want.
