The ActivationmeV fitting function can be written as:
where: - A_R - Attempt Rate - b - Barrier energy - E - activation energy - k_B - Boltzmann Constant - x - is in meV
Alternatively use the ActivationK <func-ActivationK> fitting function when fitting to Kelvin.
An example of when this might be used is for examining the ion dynamics in flouride-containing polyatomic anion cathodes using muon spectroscopy [1].
