If electron temperature and electron excitation temperatures in plasmas are different, then, is there any case they will be equal or always remain unequal?

von nicht Gleichgewichts-Elektronenkonzentrationen im Induktiv
gekoppelten Argonplasma fiir die spektrochemische Analyse'

In plasmas the electron temperature is always much different from the temperature based on the mean kinetic energy of atoms , ions and small molecules.
