Optical Properties of Metals
... Since the reflectance and transmittance are related, measuring only R and T is not sufficient to determine the optical properties of material, i.e. to determine both η and κ. It is necessary to measure also the absorbance within the material for a certain thickness. This would yield the value for th ...

Cross section (physics)
The cross section is an effective area that quantifies the intrinsic likelihood of a scattering event when an incident beam strikes a target object, made of discrete particles. The cross section of a particle is the same as the cross section of a hard object, if the probabilities of hitting them with a ray are the same. It is typically denoted σ and measured in units of area.In scattering experiments, one is often interested in knowing how likely a given event occurs. However, the rate depends strongly on experimental variables such as the density of the target material, the intensity of the beam, or the area of overlap between the beam and the target material. To control for these mundane differences, one can factor out these variables, resulting in an area-like quantity known as the cross section.
