Abstract TheL-subshell conversion for 77 keV transition andK,L 1,L 2-shell conversion for 191 keV transition in197Au, as well asK-shell conversion transition of 158 keV in199Hg were measured by means of Π√2-iron free electron spectrometer. Relative gamma-ray intensities have been determined by Ge(Li) spectrometer. From these measurements the α K conversion coefficient value has been deduced for 191 keV transition as αK(191 keV)=0.86±0.03. This value shows that the spin of the level at 268 keV in197Au is 3/2+. For the penetration parameter (λ) and intensity ratio $$\left( {\delta ^2 = \frac{{\left\langle {E2} \right\rangle ^2 }}{{\left\langle {MI} \right\rangle ^2 }}} \right)$$ the following values are obtained: $$\begin{gathered} \lambda = 3.4 \pm _{1.5}^{1.9} \delta ^2 = 0.11 \pm 0.03for 77 keV transition \hfill \\ \lambda = 3.2 \pm _{0.6}^{0.8} \delta ^2 = 0.17 \pm 0.04for 191 keV transition. \hfill \\ \end{gathered} $$ The agreement of these results with the predictions of De Shalit model is discussed.
