Cette dernière découverte, importante pour le développement de la théorie des quanta, lui valut le prix Nobel de physique pour 1919" ------ "The electric analogue to the Zeeman effect was observed by Johannes Stark at Aachen in 1913 by the use of canal rays. Hydrogen spectral lines in an electric field were resolved into a group of lines lying close to each other. This is called the Stark effect . Stark received the Nobel prize in 1919".

‎First appearance of Stark's extensive paper and most detailed paper on the Doppler-effect. In 1919 he was awarded the Nobel Prize in physics: ""for his discovery of the Doppler effect in canal rays and the splitting of spectral lines in electric fields"".""With the relatively elaborate equipment available to him in his own laboratory at Aachen, Stark completed his research in progress, chiefly on the dissymmetry of Bremsstrahlung, and undertook new series of experiments on the splitting of spectral lines in an electric field. While at Göttingen he had been encouraged by Woldemar Voigt to investigate this electrical analogy to the magnetic Zeeman effect. Stark’s first preparatory experiment, at the beginning of 1906, had been a failure"" but he was successful in October 1913. He described the experiment in a short autobiographical account. Having procured all the necessary equipment -""a high-intensity spectrograph of rather large dispersion, high-tension sources, and Gaede pumps"" - he looked for the effect ""simultaneously in the hydrogen and helium lines."" An electric field of between 10,000 and 31,000 volts/cm, was established in the canal-ray tube."" (DSB)‎

‎First appearance of these 5 important papers in which Stark describes his researches on the effects of the electrical field on the spectral lines of hydrogen, thus discovering the splitting of the spectral lines, THE STARK-EFFECT. This effect was incorporated into quantum mexhanics by Paul Epstein in 1916, and it was shown to be consistent with wave mechanics by Schrödinger in 1926. In 1919 Stark was awarded the Nobel Prize for physics for his discovery of the Doppler effect in canal rays and of the splitting of spectral lines inan electric field (the papers offered). ""At the beginning of July 1913, several months before Stark’s discovery, Niels Bohr published his concept of a quantum-mechanical model of the atom. This provided, in principle, the possibility of understanding the reason for the Stark effect, which the classical theory was powerless to explain. Stark therefore had an opportunity to be doubly gratified, having also been one of the first, after Max Planck and Einstein, to stress the “fundamental significance” of Planck’s elementary law (since 1907). which he had championed in many polemical discussions. Yet, almost incomprehensibly, Stark denied himself the satisfaction of seeing his own experiments confirm a theory for which he had helped prepare the way conceptually, even if he had not directly participated in its creation. Apparently he always had to oppose the accepted point of view. Thus, as Bohr’s theory continued to gain adherents in 1914-1916."" (DSB)‎

‎1 set of stapled pages, Planetary and Space Science, Pergamon, 2001, pp. 511-522. With a handwritten card.‎

‎Nice copy for this off-print with a handwritten accompanying cardboard sent to Dr. Jacques Lacroix. J.-L. Steinberg was a founding father of radioastronmy in France. His friend, J. Lacroix, had prepared a Ph.D (Univ. of Paris) under his leadership, in the early 60s. They worked together on experiences in the field of radioastronomy that were performed in the year 1964-1966 with "Rubis" rockets. These rockets, which were the fist 100% French expandable launch system, were launched from French-owned Hammaguir launch site, in Western Sahara. In the accompanying card, J.-L. Steinberg briefly explained that this publication was a summary of his career as a scientist. This text is an impressive and very interesting overview on his own life, by a man who was a survivor of nazis camps (most of his family was murdered in Auschwitz or on the way to Dora).‎

It should be treated as a spinning top with a magnetic needle in its axis."" ( Brandt.

‎Scarce offprint of Stern's first publication of his famous and groundbreaking series of papers named Untersuchungen zur Molekularstrahlmethode (U.z.M.), which established the field of molecular beams. In the first of the U.z.M.-papers (the present), Stern explains the advantages and disadvantages of the method, discusses technical details, and then gives the program for future work. In this section he mentions 1, the measurement of magnetic moments of molecules, including those due to the electrons, to the nucleus, and those induced by diamagnetic action" 2, electric dipole moments, including the so-called permanent dipole moment as well as moments of higher order (quadrupoles) 3, the measurement of the field of force of molecules (molecular forces) 4, fundamental problems such as the recoil on emission of a quantum, the de Broglie waves of matter, and others. The execution of this immense program kept him busy and gave work to many assistants, students, postdoctoral fellows, and guests of his institute.This series reached 30 papers before it ended prematurely due to interruption by Nazi Germany.‎

‎Berlin, Julius Springer, 1926. 8vo. Bound in a contemporary half cloth. Small Library label pasted on to pasted down front free end-paper. Library stamt to title-page. A nice and clean copy. [Heisenberg:] pp. 499-518. [Stern:] Pp. 751-763. [Entire volume: VIII, 948 pp.].‎

‎First printing of Stern's first publication of his famous and groundbreaking series of papers named UNTERSUCHUNGEN ZUR MOLEKULARSTRAHLMETHODE (U.z.M.), which established the field of molecular beams. In the first of the U.z.M.-papers (the present), Stern explains the advantages and disadvantages of the method, discusses technical details, and then gives the program for future work. In this section he mentions 1, the measurement of magnetic moments of molecules, including those due to the electrons, to the nucleus, and those induced by diamagnetic action 2, electric dipole moments, including the so-called permanent dipole moment as well as moments of higher order (quadrupoles) 3, the measurement of the field of force of molecules (molecular forces)" 4, fundamental problems such as the recoil on emission of a quantum, the de Broglie waves of matter, and others. The execution of this immense program kept him busy and gave work to many assistants, students, postdoctoral fellows, and guests of his institute.This series reached 30 papers before it ended prematurely due to interruption by Nazi Germany.ÜBER DIE SPEKTRA VON ATOMSYSTEMEN MIT ZWEI ELEKTRONEN. First edition of this important paper in which Heisenberg - after inventing Quantum Mechanics the year before (1925) - investigates some of the fundamental aspects of the new theory. Heisenberg recognizes the invariance of the wave equation with respect to various transformations. ""It is clear that such invariance exists with respect to an interchange of the coordinates of identical particles, e.g. of two electrons in an atom of two nuclei of the same kind in a molecule. As a consequence, the wave function of a non-degenerate stationary state must either remain unchanged or may only change sign when the transformation is applied to it....Indeed, in this way Pauli's exclusion principle for electrons found a formulation in terms of wave mechanics.""(K. Kronik in Memorial Volume to Wolfgang Pauli).‎
