Question: Explain why there are always two photons created in pair
Explain why there are always two photons created in pair annihilation. Why cannot the process create just one photon?
Answer to relevant QuestionsHow would the radius for the maximum probability in Fig. 28.3a change if the charge on the proton in the hydrogen atom were suddenly decreased? Explain your reasoning. (a) What is the de Broglie wavelength of the Earth in its orbit about the Sun? (b) Treating the Earth as a de Broglie wave in a large “gravitational” atom, what would be the principal quantum number, n, of its orbit? ...(a) Which has more possible sets of quantum numbers associated with it, n = 2 or ℓ = 2? (b) Prove your answer to part (a). An electron and a proton each have a momentum of 3.28470 x 10-30 kg ∙ m/s ± 10-30 kg ∙ m/s. (a) The minimum uncertainty in the position of the electron compared with that of the proton will be (1) larger, (2) the same, ...What is the energy of the photons produced in proton–antiproton pair annihilation, assuming that both particles are essentially at rest initially?
