This result contradicts Ref. 10, where (Formula presented) and (Formula presented) behavior has been observed only after introducing a prefactor of the form (Formula presented) If our data is plotted with a temperature-dependent pre- factor of the form (Formula presented) with either (Formula presented) or (Formula presented) does not exhibit (Formula presented) or (Formula presented) behavior.
