SCHRODINGER, Erwin. "Uber den Comptoneffekt" and "Der Energieimpulssatz der Materiewellen", two papers in Annalen der Physik, volume 82 pp. 257-264, and pp. 265-272; offered in the whole volume of viii, 1168 pp., with 14 plates, printed in 1927. Bound in library cloth with a few usual ex-library markings; the text though is clean and fine, very attractive copy in a solid binding. Near-fine overall. $275
Schrödinger introduces his treatment of the Compton effect (“...the increase in wavelength of X-rays and other energetic electromagnetic radiations that have been elastically scattered by electrons; it is a principal way in which radiant energy is absorbed in matter. The effect has proved to be one of the cornerstones of quantum mechanics, which accounts for both wave and particle properties of radiation as well as of matter”--Encyclopedia Britannica) in which he uses the the Klein-Gordon (“...the linear partial differential equation which is the equation of motion of a free scalar field of possibly non-vanishing mass mm on some (possibly curved) spacetime (Lorentzian manifold”--Ncat Lab) formulation of his wave equation to demonstrate the conservation of energy in quantum mechanics.
