| Abstract: | The theoretical investigations of electric field gradient (EFG) and asymmetry parameter (ν) for cubic dilute alloys are reviewed.
The valence and size EFG's and the Sternheimer antishielding factor are discussed in detail. The calculations of EFG and ν
for simple and transition metal (TM) dilute alloys of aluminium and copper, TM dilute alloys of vanadium and trinary dilute
alloys of noble metals are summarized. It is emphasized that the size EFG is as important as the valence EFG to calculate
the total EFG and ν, which are compared with the experimental values. An epilogue for further investigations is added. |
