The thermionic properties of chromium
H. B. Wahlin
The spectral emissivity, the temperature scale, and the electron work function of chromium have been determined. The emissivity is found to be 0.334 for a wave-length of 6690A and the value found for the electron work function is 4.60 volts with an A for Richardson's equation of 48 amp/cm2/T2. © 1948 The American Physical Society.
