Returning to the Stark effect, let us examine the effect of an external electric field on the energy levels of the states of a hydrogen atom. There are four such states: an state, usually referred to as, and three states (with), usually referred to as 2P. All of these states possess the same unperturbed energy,.

The n = 2 level of the hydrogen atom is 4‐fold degenerate with energy ‐0.125 E h. In terms of the quantum numbers these states are , , , and . 2010-4-21 · Stark Effect Robert Gilmore Physics Department, Drexel University, Philadelphia, PA 19104 April 21, 2010 Abstract An external electric field E polarizes a hydrogen atom. This lowers the ground state en-ergy and also partly breaks the N 2-fold degeneracy of the N hydrogenic states ψNLM(x) = hx|NLMi with principal quantum number N. 2021-4-13 · At electric field intensities of 100,000 volts per centimetre, Stark observed with a spectroscope that the characteristic spectral lines, called Balmer lines, of hydrogen were split into a number of symmetrically spaced components, some of which were linearly polarized (vibrating in one plane) with the electric vector parallel to the lines of force, the remainder being polarized perpendicular to the direction of the field except when viewed along the field.

The energy shift due to the electric field is called the Stark effect. Stark Effect in Hydrogen and Deuteriuum 351 sufficient for H,D, and two for HiD8. The dispersion varied from 12 2 A/mm. for Ha to 7 0 A/mm. for H8. Exposures lasted from 30 to 60 min. The intensities of components may be estimated from the photographs reproduced in Plate 19. Under our experimental arrangement, we con- The theory of the Stark effect given by Schwarzschild and Epstein is adequate provided that the electric separation is so much larger than the fine-structure separation of the unperturbed levels that the latter may be regarded as single; but in weak fields, when this is no longer so, a supplementary investigation becomes necessary.
