Abstract
It is shown that Fermi's golden rule is valid for any initial state having a very narrow energy spread even if it is not an eigenstate of the free Hamiltonian. As an example, the author computes explicitly the tunnelling rate through a rectangular barrier. This method may have application in the Stark effect, autoionisation, fission, and similar problems.Keywords
