In this article, a method is devised to study the energy spectrum for an excited electron configuration in an ideal crystal. The configuration studied consists of a single excited electron taken out of a full band of N electrons. The multiplicity of the state is N 2 . It is shown that because of...
The mobility spectrum of spray electrified salt solutions has been investigated with an Erikson mobility tube under conditions of high resolving power. In general there are no charged carriers of mobility greater than 1.7 cm/sec. per volt/cm. At about this value the curves rise sharply, and then...
The ionization occurring in mercury vapor as the result of the impact of electrons of energy less than 10.4 volts was studied by use of a tube containing a small filament, the emission of which was limited by space-charge. The ionization produced has been studied as a function of electron...
The discrete levels of the electrons of a metal, lying below the continuum of levels predicted by the energy band theory, and interpreted in an earlier paper as leading to the superconducting state, have been further investigated, though a quantitative discussion in the general case is still...
For a gaseous discharge in which the ions have a drift velocity superimposed on a Maxwellian distribution, the Mott-Smith and Langmuir collector theory deals only with collectors having a high ratio of sheath to collector diameters. The present paper removes this restriction, but points out that...
The rotation spectrum of water vapor has been measured with high dispersion from 18μ to 75μ. The spectrometer employed echelette gratings and higher spectral orders were successfully removed through the use of filters and selective reflection. The positions of single lines were determined with...
