Hi Gabriele,
To qualify Anatoly's cheerful, pre-morning coffee response, if your samples are part of a sequence of measurements
of a material whose XANES has been measured at different temperatures, and said XANES does have some changes
owing to changes in physical or electronic behavior with temperature (i.e. a phase transition), then you could estimate
where your samples fit within that determined behavior.
Are you familiar with how temperature dependence manifests in a typical XAFS measurement?
...through the Debye-Waller term..the effects of which become less pronounced at lower k...
Temperature is more typically a controlled parameter during measurements.
So no, not really...unless there is a known behavior for comparison.
