Measurements of mass attenuation coefficients for 51Sb over energy region 4 keV–14 keV using synchrotron radiation

In the present work, the X-ray mass attenuation coefficients have been measured for 51Sb (a medium-Z element) at forty energies across its Li (i = 1–3) sub-shell absorption edges covering an extended energy region within 4.0 keV–14.0 keV. The aim of this study is to experimentally determine the key...

Zusammenfassung:In the present work, the X-ray mass attenuation coefficients have been measured for 51Sb (a medium-Z element) at forty energies across its Li (i = 1–3) sub-shell absorption edges covering an extended energy region within 4.0 keV–14.0 keV. The aim of this study is to experimentally determine the key X-ray fundamental parameters for 51Sb with improved accuracy by using tunable energy synchrotron radiation. From the present measured mass attenuation coefficients, the Li (i = 1–3) sub-shell photoionization cross sections (σLiP) have been deduced at twenty four energies across the Li (i = 1–3) edge-energies of 51Sb covering the region 4.150 keV–5.0 keV by using experimentally deduced Li (i = 1–3) edge jump ratios. Two theoretical datasets of X-ray mass attenuation coefficients and total photoionization cross sections were served to evaluate their consistency with the present experimental values and reveal possible discrepancies, in particular, across the Li (i = 1–3) edge-energies of 51Sb. •Mass attenuation coefficients measured at forty energies across Li (i = 1–3) edges of 51Sb.•Li (i = 1–3) edge jump ratios deduced from measured data.•Li (i = 1–3) sub-shell photoionization cross sections deduced from measured data.
