Do Fermi and Gamow-Teller transitions only refer to changes in isospin , as in beta decay and orbital electron capture

A Fermi transition is a type of radioactive decay in which a nucleus undergoes a change in its number of protons or neutrons, while also emitting a neutrino or antineutrino. These transitions are named after Enrico Fermi, who first described them in the 1930s.
A Gamow-Teller transition is a type of beta decay in which a nucleus changes its spin and/or parity, while also emitting a neutrino or antineutrino. These transitions are named after George Gamow and Edward Teller, who first described them in the 1930s.
No, Fermi and Gamow-Teller transitions refer to a type of nuclear decay and are not limited to just isospin. However, they do involve changes in isospin, which is a quantum number that distinguishes between protons and neutrons.
Fermi and Gamow-Teller transitions are both types of beta decays, but they differ in their selection rules. Fermi transitions are allowed for all nuclei, while Gamow-Teller transitions are only allowed for nuclei with a spin of 1/2. Additionally, Gamow-Teller transitions have a higher probability of occurring than Fermi transitions.
Yes, Fermi and Gamow-Teller transitions can be observed experimentally through various techniques such as beta decay spectroscopy and electron capture spectroscopy. These methods allow for the detection and measurement of the energies and momenta of the particles emitted during these transitions, providing evidence for their occurrence.
