The new energy levels and wavefunctions could in principle be found by writing down a complete Hamiltonian, including the external field, and finding the eigenkets. The Stark effect is the electric analogue of the Zeeman Effect where a spectral line is split into several components due to the presence of a magnetic field. The Stark effect can be explained with fully quantum mechanical approaches, but it has also been a fertile testing ground for semi classical methods. History. The effect is named after Johannes Stark, who discovered it in 1913.It was independently discovered in the same year by the Italian physicist Antonino Lo Surdo, and in Italy it is thus sometimes called the Stark-Lo Surdo effect.The discovery of this effect contributed importantly to the development of quantum theory.

Stark effect quantum mechanics

The fact that an electric field applied to the source will bring out the combination lines 2 p — mp was discovered by Koch in 1915. The Stark effect is the phenomena of altering atomic energy levels by an external electric field. The external electric field can be applied to an atom or molecule and acts as a perturbation. This effect, though small compared to the spacings between the unperturbed atomic levels, is quite significant. The Stark effect can be readily observed as PDF | The Non-Hermitian aspect of Quantum Mechanics has been of great interest recently.

The Hamiltonian of the H-atom thus has (another) additional term, the Stark term H Stark, which is perturbing the Coulomb Hamiltonian H 2014-04-21 If an atom (not necessarily in its ground state) is placed in an external electric field, the energy levels shift, and the wavefunctions are distorted. This is called the Stark effect. The new energy levels and wavefunctions could in principle be found by writing down a complete Hamiltonian, including the external field, and finding the eigenkets.
