Selection rules physics
WebMay 11, 2024 · Most often, selection rules help us specify what happens to the atom upon interaction with a photon, which has spin angular momentum of norm 2 ℏ, and a projection of ± ℏ. (The orbital angular momentum of a photon is beyond the scope necessary for atomic-physics.) WebA selection rule is a quantum mechanical rule that describes types of quantum mechanical transitions that are permitted. Transitions not permitted by selection rules are said to be …

WebApr 10, 2024 · Rules that determine which transitions between different energy levels are possible in a system, such as an elementary particle, nucleus, atom, molecule, or crystal, … WebA selection rule is a quantum mechanical rule that describes types of quantum mechanical transitions that are permitted. Transitions not permitted by selection rules are said to be "forbidden," although in practice, such transitions are generally forbidden "to first order" only, which means they may occur in practice but with low probabilities.
