Due to charge conservation, this type of beta decay involves the release of a charged particle called a “positron” that looks and acts like an electron but has a positive charge.

WebIf the photon is near an atomic nucleus, the energy of a photon can be converted into an electron–positron pair: (Z+) γ → e − + e + The photon's energy is converted to particle mass in accordance with Einstein's equation, E = m ⋅ c2; where E … Web3. Ionization Ionization by electron impact is fundamentally different from ionization by positron im- pact. Since the ejected electron is of the same species as the impacting particle, EII is a non-particle-conserving process, i.e., the indistinguishability of electrons leads to a gain in the number of electrons in the swarm.
