Fermi's Golden rule is used to calculate the probability (per unit time) of a quantum mechanical transition between two quantum states. Although Fermi first coined the term "Golden Rule", Dirac developed most of the machinery.
where
- = initial quantum state of the system
- = final quantum state of system after a transition
- = part of the Hamiltonian which is responsible for the transition.
- integration over all space
