Minneapolis, Minn., The Physicalreview, 1926. 4to. Contemp. full buckram. Small tear to first hinge at foot. A stamp in upper right corner on titlepage and 2 other pages. In: "The Physical Review. Conducted by the American Physical Society", Vol. 28, Second Series. VI,1343 pp. (Entire volume offered).Schrödinger's paper: pp. 1049-1070. Internally clean and fine.

First appearance of the first treatment of Wave Mechanics in English.The paper reviews Schrödinger's own wave-mechanics and De Broglie's "phase waves", and covers all the results Schrödinger had hitherto obtained in his main communications of 1926 (the 3 papers in German). An English translation of Schrödinger's main papers was not published until 1928.

"The paper gives an account of the author's work on a new form of quantum theory. §1. The Hamiltonian analogy between mechanics and optics. §2. The analogy is to be extended to include real "physical" or "undulatory" mechanics instead of mere geometrical mechanics. §3. The significance of wave-length; macro-mechanical and micro-mechanical problems. §4. The wave-equation and its application to the hydrogen atom. §5. The intrinsic reason for the appearance of discrete characteristic frequencies. §6. Other problems; intensity of emitted light. §7. The wave-equation derived from a Hamiltonian variation-principle; generalization to an arbitrary conservative system. §8. The wave-function physically means and determines a continuous distribution of electricity in space, the fluctuations of which determine the radiation by the laws of ordinary electrodynamics. §9. Non-conservative systems. Theory of dispersion and scattering and of the "transitions" between the "stationary states." §10. The question of relativity and the action of a magnetic field. Incompleteness of that part of the theory." (From the Abstract in front of the paper).
