The Spectrum of the Penetrating alpha-Rays from Radium B and Radium C. SS. 263-273. Mit 2 Abbildungen und 1 Tafel. In: Philosophical Magazine and Journal of Science. 6th series. Vol. 28.
London, Taylor & Francis, 1914. - (22 x 14,5 cm). VII, 848 S. Mit 14 teils gefalteten Tafeln. Halbleinwand der Zeit.
Erste Ausgabe von Rutherfords berühmter Abhandlung über den Nachweis der Welleneigenschaften der Gamma-Strahlen und dass verschiedene Isotope eines Elements tatsächlich der gleichen Ordnungszahl im Periodensystem zugeordnet werden können. "This year (1914) saw the publication by Rutherford and Andrade of a piece of work great beauty. When a beam of gamma rays from radium B and C impinged on a thin sheet of mica, those rays which struck the crystals of the mica at a suitable angle were enhanced in a certain direction and impoverished in another, so that a photographic film behind the mica appeared to be ruled with four bright lines forming a square, and with four dark lines forming another square. By measuring the deflection of the gamma rays it was possible to determine their wave lengths, which are comparable with those of X-rays, but usually shorter, though the range of values is large" (Eve, Rutherford). - Stempel auf Vorsatz. Einband stellenweise etwas berieben, sonst gut erhalten. - DSB 12, 25
