N2 - Fe57 γ-ray resonance-absorption spectra in crystals of the iron-storage protein, ferritin, display above 265°K, in addition to a normal quadrupole doublet, wide Lorentzian wings extending to velocities of ± 2 cm/sec. The results are interpreted in terms of the dynamics of the iron-containing core of the protein, undergoing bounded diffusive motion within a "cage," characterized by a jump probability per unit time of about 0.5×108 sec-1 and a mean-square displacement of about 4.8×10-22 at 298°K.
