Determination of LIII subshell absorption jump ratio and jump factor of wolfram

• This work regards the LIII subshell absorption jump ratio and jump factor of wolfram.
• These parameters were obtained using two different methods.
• The results are in good agreement with theoretical and experimental values.

The LIII subshell absorption jump ratio and jump factor of wolfram have been measured by two different methods. In the first method the mass attenuation coefficients have been obtained by narrow beam transmission geometry to calculate the LIII subshell absorption jump ratio and jump factor. In the latter these parameters have been derived from the LIII subshell X-ray production and the photoionization cross sections of the LIII subshell and higher subshells determined by Energy Dispersive X-ray Fluorescence technique and narrow beam transmission geometry, respectively. The results obtained by both methods have been compared with theoretical and experimental values. They are in good agreement with each other.
