WebMay 24, 2024 · 4. Why can a neutral pion decay into 2 photons but not one? It is due to the law of conservation of energy and momentum. A particle with a given mass cannot "decay" to only one smaller mass particle because the decay to one particle at the center of mass would not conserve energy, unless it was in motion, which would not conserve momentum. WebFor example, the energy per photon at the 351-nm excimer line (XeF) is 3.53 eV, while the energy per photon at the 193-nm excimer line (ArF) is nearly double at 6.42 eV. The …
