Internal conversion study on the contact charge density of57Fe impurity atoms in Au metal

Three different internal conversion spectra were measured on the 14.4 keV transition of⁵⁷Fe in Au metals. Adaptability of our method for analysing the line intensity, i.e. the deconvolution-reconvolution method with the constant tail fraction rule was tested experimentally. The obtained 4s electron densities, 4_s(o), of Fe impurity atoms in Au agreed on four samples within the error. The weighted mean value of 4_s(o) of Fe in Au is 4.98±0.68a ₀ ^–3 . It is concluded that the method of analysis is reasonable in this type of experiment.
