Absorber-Thickness Effect Versus Goldanskii-Karyagin Effect inSb121Mössbauer Quadrupole Patterns

Abstract

From a detailed analysis of the Mössbauer quadrupole spectra of ${\mathrm{S}\mathrm{b}\left(\mathrm{C}{\mathrm{H}}_3\right)}_3$ ${\mathrm{Br}}_2$ measured using the 37.15-keV $\gamma$ ray of ${}_{}{}^{121}{}_{}{}^{}\mathrm{Sb}$, it is shown that the large Goldanskii-Karyagin effect reported in this compound is not conclusive; the spectra are well accounted for by a transmission integral to include the absorber-thickness effects. Such an analysis also yields an $e^2{q}_{z}Q$ in agreement with nuclear-quadrupole-resonance measurements.
