The vacancy transfer probabilities from K to L shell through radiative decay, 𝜂KL , have been deduced for the elements in the range $19 \leq Z \leq 58$ using K-shell fluorescence yields. The targets were irradiated with 𝛾 photons at 59.5 keV from a 75mCi 241Am annular source. The K X-rays from different targets were detected with a high resolution Si(Li) detector. The measurement of vacancy transfer probabilities are least-squared fitted to second-order polynomials to obtain analytical relations that represent these probabilities as a function of atomic number. The obtained results agree with theoretical and fitted values.
