Infrared absorption by localized polarons in the silver halides
The infrared absorption of silver halide crystals, induced by simultaneous illumination of the crystals with light whose energy exceeded the indirect band gap, was measured from 33 to 2000 cm-1 at temperatures from. 90 K to 40 0 K. The induced far infrared absorption was shown to be in agreement …

Optical absorption of pure and mixed silver halides a low temperatures
The low level indirect optical absorption of pure AgCl and AgBr has been measured between 4.20 K and0 77 K . The corresponding indirect optical absorption of AgCl~AgBr mixed crystals has also been measured in the same temperature range. The temperature dependence of the absorption spectra of pure …

Optical absorption measurements on silver halides in the ultraviolet and extreme ultraviolet energy ranges
The absorption coefficients of silver chloride and silver bromide have been determined from thin film transmission measurements in the range of photon energy from 3.5 to 6.7 electron volts and from 30 to 240 electron volts. An unusual feature of this work is the use of electron synchrotron …

Geology, geochemistry, and genesis of the El Peñón epithermal Au-Ag deposit, northern Chile : characteristics of a bonanza-grade deposit and techniques for exploration
The El Peñón gold-silver deposit comprises six epithermal veins, which contain a geologic resource (measured + indicated + inferred) of 3.8 million oz Au and 63 million oz Ag. The deposit is hosted in Paleocene and Eocene mafic to felsic volcanic rocks and is located in the central portion of the …
