The most common and most important result of them is that the nature and size of the effect on corresponding series of different elements are largely an expression of the peculiarity of their atomic structure – or, at least, of the structure of the surface. Johannes Stark Read Quote
The removal of an electron from the surface of an atom – that is, the ionization of the atom – means a fundamental structural change in its surface layer. Johannes Stark Read Quote
If the experimental physicist has already done a great deal of work in this field, nevertheless the theoretical physicist has still hardly begun to evaluate the experimental material which may lead him to conclusions about the structure of the atom. Johannes Stark Read Quote
The emitters of the spectral series are without exception single atoms, not compounds of atoms. Johannes Stark Read Quote
Thus at the beginning of 1906 it seemed to be established that the emitters of the spectral series of chemical elements are their positive atomic ions. Johannes Stark Read Quote
We can in fact first place the beam of rays of moving positive atomic ions in a plane perpendicular to the axis in which we see the spectral lines emitted by them. Johannes Stark Read Quote
The movement of the emitters of the spectral lines may be deduced on the basis of the Doppler principle. Johannes Stark Read Quote
It is more likely that more than a century will pass before we know the structure of the chemical atoms as thoroughly as we do our solar system. Johannes Stark Read Quote
By allowing the positive ions to pass through an electric field and thus giving them a certain velocity, it is possible to distinguish them from the neutral, stationary atoms. Johannes Stark Read Quote
With this in mind, for some twenty years I have set myself as my particular task the experimental investigation of the connexion between change in the structure and change in the spectra of chemical atoms. Johannes Stark Read Quote
