摘要：

We have calculated the overlap contribution to the contact charge density at the57Fe3+ site in fluoride and oxide lattices, FeF3, CaFe2O4, CaBaFe4O8 and KFeO2. The trend in isomer shifts in going from one lattice to another is explained in terms of the overlap effects. The experimental values of the change in isomer shift from lattice to lattice is used to obtain the change in nuclear size. The values of δr/rN are found to lie between -0.81×10-4 and -1.56×10-4. © 1979 North-Holland Publishing Company.
