Two photon decay

Why can a particle decay into two photons but not one?

WebA particle in the excited state can spontaneously emit a photon and decay to the ground state. The rate at which this happens is described by the Einstein coefficient A 10, which has units of s-1. Its meaning is simply that a population of n 1 atoms in the excited state will decay to the ground state by spontaneous emission at a rate WebThe results in terms of the kinetic energy and angular distributions of the charged particles show unambiguous experimental evidence of intermolecular Coulombic decay (ICD) in carbon dioxide dimers. In the oxygen dimer, the results show that ICD is accompanied by knock-off ionization mechanisms. View on External Site. Item not freely available?
