Abstract

Abstract: In the present work, the X-ray mass attenuation coefficients have been measured for 51 Sb (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 51 Sb 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 ( σ L i P ) have been deduced at twenty four energies across the Li (i = 1–3) edge-energies of 51 Sb 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 51 Sb. Highlights: Mass attenuation coefficients measured at forty energies across Li (i = 1–3) edges of 51 Sb. Li (i = 1–3) edge jump ratios deduced from measured data. Li (i = 1–3) sub-shell photoionization cross sections deduced from measured data.
