Optical absorption of copper and silver at 4.2°K
Manfred A. Biondi
Measurements of the optical absorption of copper and silver are made over the wavelength range 0.3-3.3μ at a temperature of 4.2°K where the classical mean free path of the conduction electrons is much greater than the depth of penetration of …

COPPER: Angular spectral absorptance
Band structure of noble metal alloys: Optical absorption in α-brasses at 4.2°K
M. A. Biondi, J. A. Rayne
Calorimetric optical absorption measurements at 4.2°K have been made on a representative series of α brasses over the wavelength range 0.23 to 4.0 microns using electropolished bulk specimens. Changes in the absorption spectrum below 6000 A are interpreted in the …

The Melting Point-Composition Diagram of the Zirconium-Oxygen System
Daniel Cubicciotti
The solidus curve of the zirconium-zirconium dioxide system has been investigated by observing the melting points of wires of the oxidized metal. The results show that near the melting points oxygen dissolves to the extent of 55 atom per cent. …

Solar reflectance integrating sphere
R. V. Dunkle, D. K. Edwards, J. T. Gier, J. T. Bevans
An inexpensive integrating sphere for the direct determination of the reflectance of materials irradiated by solar energy transmitted through the atmosphere of the earth is described. Reflectance and transmittance measurements of various metals, cloths, and filters are reported and are …
