3.3.1.154. NXtfy

Status:

base class, extends NXobject

Description:

Total fluorescence yield (TFY) mode XAS. The absorption coefficient ...

Total fluorescence yield (TFY) mode XAS. The absorption coefficient is proportional to the ratio of the total fluorescence intensity and the incident beam intensity:

\[\mu(E) \propto I_f/I_0\]

Symbols:

nEnergy: Number of energy data points
