Gammow-Teller Operator

The Gammow-Teller operator describes a specific type of nuclear process where a proton in an atom's nucleus transforms into a neutron, or vice versa, by exchanging a type of particle called a beta particle. This operator is essential in understanding certain types of radioactive decay and how atomic nuclei change their composition. It involves both the spin and isospin properties of particles, meaning it considers their intrinsic angular momentum and their identity as protons or neutrons. Essentially, the Gammow-Teller operator governs the probability and nature of these weak-force-driven nuclear transitions.
