## Konfigurationsraum und zweite Quantelung (Fock, pp. 622-647) WITH Über die Photodissoziation von Atommolekülen in Ionen (Terenin & Popov, pp. 338-339) in Zeitschrift Für Physik, 75, 1932

Berlin: Julius Springer, 1932. 1st Edition. FIRST EDITION (ENTIRE VOLUME), INCLUDING VLADIMIR FOCK’S ‘FOCK’S SPACE’ PAPER, an “elegant” and important description of “the space of states for quantum systems with an arbitrary (infinite) number of particles” (Pais; Chronology of Milestone Events in Physics). ALSO INCLUDED, TERENIN & POPOV’S PHOTOION-PAIR FORMATION paper presenting the first “application of mass analysis to photoionization studies” Williams, Molecular Physics, 539).

The Soviet physicist Vladimir Fock “did foundational work on quantum mechanics and quantum electrodynamics” (Wikipedia). Mehra, The Conceptual Completion and Extensions of Quantum Mechanics, 763). Fock’s paper relates “the method of second quantization in nonrelativistic quantum field theory and Schrödinger’s original wave equation in configuration space.

“He proceeded in two steps: In Part I, he established the ‘second quantized’ wave functions, the wave function operators from the Schrödinger function according to the prescription of Jordan and Klein and Jordan and Pauli… The starting point of the considerations of Part II constitute the commutation of relations between the quantized wave functions (wave function operators)” (Mehra, Conceptual Completion and Extensions of Quantum Mechanics, 763). Fock created two operators (wave function and wave function +); the first leads from a function of n variables to a function of (n-1) variables; the latter from a function of (n-1) variable to a function of n variables. “This formalism constituted what one later called the ‘Fock-space representation’, with wave function and wave function + denoting creation and annihilation operators, respectively. Later on, this representation would play an important role in relativistic quantum field theory” (Mehra, The Conceptual Completion and Extensions of Quantum Mechanics, 763).

In their paper, two Russian physicists Terenin and Popov were the first to achieve “mass analysis of the product ions from interactions between photons and molecular beams” (Advances in Atomic and Molecular Physics, 142). After “systematic research of photoprocesses in rarefied vapours of salts and simple molecules” Terenin and Popov used mass-spectroscopy to demonstrate “the formation of ion pairs in the photoionization of thallium halides” (Science Direct; Williams, Molecular Physics, 539). Item #1504
