WebbPair production is a process in which a gamma ray of sufficient energy is converted into an electron and a positron. A fundamental law of mechanics, given by Newton, is that in any process total linear (as well as angular) momentum remains unchanged. In the pair-production process a third body is required for momentum conservation. When that … Webb9 apr. 2024 · The emission of a single or multiple gamma rays brings this daughter nucleus to its ground state. The beta decay of 60 27 Co produces 60 28 Ni. The daughter nucleus (60 28 Ni) is in its excited state. By emitting two gamma rays with energies of 1.17 MeV and 1.33 MeV, this excited nucleus returns to its ground state.
