Ex library Carnegie Institution of Washington Mount Wilson Observatory with call number gilt stamped on spine and library blind-stamp on front free end paper. Clean copy. FINE. RARE. FIRST EDITION. This is the first paper in the Zeitschrift fur physik in which Geiger and Bothe published the results of their collaboration which began in November 1913 at the Physikalisch-Technische Reichsanstalt in Berlin. In 1908 Geiger and Rutherford investigated the charge and nature of the ( particle. They devised an electrical technique in order to count the individual ( particles and compare results with those obtained by Erich Regener, who used the scintillation technique. Their ionization chamber was a cylinder at low pressure with a thin wire stretched coaxially. The wall of the cylinder had an entrance window at one end and was at high negative potential to the wire. An ( particle entering parallel to the wire generated a secondary avalanche, multiplying the primary ionization effect a thousandfold. The resulting voltage step on the central wire was measured by a sensitive electrometer. In October 1912, Geiger went to Berlin and continued experiments on the counting of ( particles. Varying the form and dimensions of the central electrode, he found an arrangement which came to be known as the Spitzenzahler or "point counter," since "the whole working of the apparatus depends on the point of the needle." The great advantage of this device was that in addition to ( particles, it could for the first time, count ( particles as well as other types of radiation. Geiger became the editor of the Zeitschrift fur physik beginning in 1936. DSB, V, pp. 330-333.

Soft cover. Condition: Very Good. 1st Edition. First edition of the famous Bothe-Geiger experiment, which "confirmed the existence of photons, conservation of energy and the Compton scattering theory" (Wikipedia), and for which Bothe was awarded the Nobel Prize in Physics 1954. "The discovery of the Compton effect in 1923 stirred up the physics community. It had shown that X-rays, scattered off electrons under a given angle, changed their wavelength. If one assumed that photons, like material particles, possess energy and momentum, the Compton effect could be explained easily. But this assumption at that time was hard to accept for many, in particular for Bohr. Together with Kramers and Slater he tried to reconcile quantum effects with Maxwell's theory of the electromagnetic field. In a paper entitled 'The Quantum Theory of Radiation' they tried to elaborate Planck's original idea of 1900 in which the properties of the electromagnetic field were left unchanged and all quantum effects were caused by the structure of the atoms. In what is now called the 'BKS theory', the three authors conjectured that the atom contains many virtual oscillators, one for every possible transitions between stationary states, and that these oscillators communicate with those of other atoms through virtual fields by probability laws. In that theory they had to accept, however, that energy and momentum are not conserved in each individual process but only in the statistical average . . . Shortly after the appearance of that theory in print Bothe and Geiger published a note announcing that they would test it by searching experimentally for the simultaneous appearance of a scattered photon and a recoiling electron. They devised the apparatus for what is believed to be the first coincidence experiment [the offered paper] (Brandt, Harvest of a Century, pp. 140-1). "Werner Heisenberg remained agnostic with respect to BKS theory. In a letter to Arnold Sommerfeld, he wrote: 'For the rest I believe more and more that the question 'photons or correspondence principle' is a question of semantics. All effects in quantum theory must after all have a classical counterpart, for the classical theory is almost correct; thus all effects must have two names, a classical and a quantum [name]. Which one prefers is really a matter of taste. Perhaps the Bohr radiation theory is a very happy description of this dualism; I am anxiously awaiting the results of the Bothe Geiger experiment'" (Wikipedia). Bothe and Geiger "devised a sophisticated measuring instrument consisting of two opposing needle counters. An X-ray was passed through the gap between these counters. While one of the counters responded only to the light quanta, the other registered only the recoil electrons. The deflections of the light counter and the electron counter were recorded on silver bromide film that moved past the counters at high speed. Fine strips on the film allowed the scientists to precisely record the timing of the particles as they collided. According to the authors, if a quantum of light and a recoil electron collided simultaneously and their joint impact could be measured as a coincidence, then the particle nature of light would be confirmed and the law of conservation of energy proven also at the atomic level. If, in contrast, there were a delay in the response by the two counters, that would argue against the particle nature of light and the strict validity of the law of conservation of energy, thus giving credence to the agitators in Denmark . . . Bothe and Geiger showed that, with an accuracy of one ten-thousandth of a second, the 'light counter' and the 'electron counter' responded simultaneously . . . Walther Bothe and Hans Geiger had provided one of the strongest arguments for Einstein's light quanta" (Maier, Particle billiards, captured on film, MaxPlanckResearch). 8vo, pp. 639-720.
