Orientation of electric field gradient of Fe³⁺ in aegirine by Mössbauer spectroscopy

Abstract

To reliable peak separation of Mössbauer quadrupole doublet peaks of single crystal, crystallographic orientation of electric field gradient vector of Fe site should be known. In this study, Mössbauer spectra of crystallographically oriented thin sections of aegirine were measured to determine the electric field gradient vector of M1 site in aegirine.
