CXV. Resonance absorption of nickel in the infra-red region

Abstract

Means are described whereby the absorption in the infra-red of ‘free’ or ‘conduction’ electrons may be abstracted from the total which is measured experimentally. When this is done, it is clear that there is residual absorption in nickel which may be caused by electron transitions from the d- to the s-band. The mechanism is being further explored.
