The excitation probabilities of Kα,β and Lα1,2 for some elements in 56≤Z≤68 at 59.54 keV

•The EKα,β and ELα1,2 have been determined for some elements at 59.54 keV.•The EKα,β and ELα1,2 have been obtained experimentally using the EDXRF technique.•The EKα values are seen to be 3–4 times higher than the EKβ values.•The ELα1,2 values are seen to be 5–7 times lower than the EKα values.

The Kα,β and Lα1,2 excitation probabilities for some elements in 56≤Z≤68 at 59.54 keV were obtained using a Si(Li) detector with a multichannel analyzer. It is the first time that the Kα,β and Lα1,2 excitation probabilities were determined for the present elements. To obtain the Kα,β and Lα1,2 excitation probabilities, the K and L3 shell/sub-shell absorption jump factors and the K and L3 shell/sub-shell fluorescence yields were determined experimentally. The measured results of absorption jump factor and fluorescence yield were compared with the theoretical and other experimental results. The determined excitation probabilities were compared only with theoretical calculated ones since there are no other experimental reports for the present elements in the literature.
