Abstract: Recent literature has suggested that the McCumber relation relating laser emission and absorption cross-sections is not valid for erbium:glass. We present a theoretical and experimental ...

The cross section of the ¹⁰⁹Ag(n,γ)^110mAg reaction is measured with the aid of using the neutron activation approach and γ-ray spectroscopy. Neutrons were generated with the help ...

Geologic cross sections are being constructed to better understand the silver and gold system to the northwest. Targeting is now underway to bridge mineralization on remaining 500 metres of vein ...
