The Gamow-Teller transition is a type of nuclear transition that occurs during beta decay, where a nucleus changes from one state to another by emitting a beta particle. This process involves the conversion of a neutron into a proton or vice versa, accompanied by the emission of an electron or positron and a neutrino. The transition is characterized by the change in the spin and parity of the nuclear states involved. In nuclear physics, the Gamow-Teller transition is significant because it helps explain the behavior of certain isotopes and their stability. It plays a crucial role in understanding processes like nucleosynthesis in stars and the mechanisms behind neutrino interactions.
