Many interesting features of the Stark-effect may be seen with unusual clearness in the arc spectra of helium, and these we shall mention very briefly before referring to the theory. The fact that an electric field applied to the source will bring out the combination lines 2p —mp was discovered by Koch in 1915. Since that time many investigators have shown by Lo Surdo’s method that a moderate external field is sufficient to remove all restrictions with regard to changes in the azimuthal quantum number.
