Excerpt from Characteristic Soft X-Rays From Arcs in Gases and Vapors
Experiments with radiation from solids indicate the existence of soft characteristic X-radiation, with no measurable general radiation under the best vacuum condi tions. Nickel shows radiation Starting at 80 volts.

Excerpt from Characteristic Soft X-Rays From Arcs in Gases and Vapors
The following transitions in the type of electron collisio'ns take place. Above the first ionization potential one valence electron may be ejected and the arc Spectrum is. Emitted upon recombina tion. At successively higher potentials two or more electrons may be ejected, with subsequent emission of the spark Spectra of first or higher orders.

Paperback. Condición: New. Print on Demand. This book lists the potentials required to excite successive types of radiation in gases and vapors by electron impact, measured by observing the photoelectric effect of the arc radiation on other electrodes within the same tube. The range of potentials ranges from 17 to 500 volts. The author measured critical radiating potentials for 11 gases and vapors and identified the L series limits of sodium, magnesium, phosphorus, sulphur, and chlorine. Additionally, the K series limits of carbon, nitrogen, and oxygen are identified, as well as the softest X -ray limits (M series) of potassium. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
