For 20 years it has been assumed that whistler mode waves can only resonate with electrons above a characteristic energy E{sub C} = B{sup 2}/2{mu}{sub 0}N, the magnetic energy per particle. Since this energy is typically greater than 10 keV in the outer radiation belt, it has then been argued that auroral electrons at energies less than 10 keV could not be diffused in pitch angle by interaction with whistler mode waves.
