The rate of a process is based upon the energy barrier required to cross the corresponding saddle point, and a harmonic prefactor.

Even Enrico Fermi apparently did not bother to read Hasen?hrl's papers properly before concluding wrongly that the discrepant 3/4 prefactor was due to the electron self-energy identified by Abraham.
