Formulierung des Beugungs-Problems. Endlicher Bereich. Carbon typescript.

Publisher Information: 1931.

Sommerfeld, Arnold (1868-1951).] Formulierung des Beugungs-Problems. Endlicher Bereich. Carbon typescript with manuscript additions in Sommerfeld’s hand. 29ff., numbered 1-27, 27a, 28. 330 x 210 mm. N.p., n.d. (1931). Creased horizontally, some minor marginal fraying and chipping, light soiling. Very good.

Carbon typescript of a section of Sommerfeld’s “Über die Beugung und Bremsung der Elektronen” (Annalen der Physik 11 [1931]: 257-330), with numerous manuscript equations and other additions in Sommerfeld’s hand; the section title can be translated as “Formulation of the diffraction problem: Finite area.” Sommerfeld’s paper on the diffraction and slowing down of electrons is still cited in current publications on electron microscopy, cosmic ray physics, X-ray tube spectra and related subjects.

Sommerfeld, one of the pioneers of atomic and quantum physics, was a brilliant theoretician who introduced the second (azimuthal) quantum number and the fine-structure constant, and pioneered X-ray wave theory. His application of Bohr’s revolutionary 1913 theory of the atom to the Zeeman effect and to the fine structure of spectral lines was largely responsible for the rapid and widespread acceptance of Bohr’s atomic model. The results of Sommerfeld’s investigations of atomic spectra and the Zeeman effect performed during the 1910s and 1920s were accepted almost without change in the post-1925 quantum-mechanical theory of atomic structure. Sommerfeld was equally brilliant as an educator: As the director of the University of Munich’s Theoretical Physics Institute, Sommerfeld taught and mentored many of the creators of the new quantum physics, including Nobel Laureates Werner Heisenberg and Wolfgang Pauli.
