Positive and Negative Thermionic Emission from Columbium
Autor: L. O. Sordahl, H. B. Wahlin
Publikováno v: Physical Review. 45:886-889
The positive ion and electron work functions have been determined for well outgassed columbium and found to be for the electrons 3.96 volts with A equal to 57 amp./ ${\mathrm{cm}}^{2}$/${\mathrm{degree}}^{2}$ and for positive ions 5.52 volts. It has

Positive and Negative Thermionic Emission from Tungsten
Autor: H. B. Wahlin, L. V. Whitney
Publikováno v: Physical Review. 50:735-738
The positive and negative thermionic emission and the rate of evaporation of neutral atoms have been studied for well outgassed tungsten. To fix a reliable temperature scale the spectral emissivity for $\ensuremath{\lambda}=0.669$\ensuremath{\mu} has

The Motion of Electrons in Nitrogen
Autor: H. B. Wahlin
Publikováno v: Physical Review. 23:169-177
Mobilities of electrons in nitrogen have been determined in fields ranging from 1 volt/cm to 55 volts/cm at atmospheric pressure. For low fields the mobility has a value of 18,000 cm/sec. but decreases rapidly for higher fields. The results agree for
