How many beta-positive decay happened in one cycle? … Web29 de out. de 2024 · CNO Cycle: The result is a net conversion of 4 protons into 1 Helium nucleus, with a release of energy in the form of gamma-ray photons, neutrinos, and positrons. Because 12 C is not consumed by this process (it goes in at the top & comes out at the end), we say that it acts as a catalyst in this nuclear reaction.
