Abstract 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 ( σ L i P ) 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.

摘要 在目前的工作中，已经测量了 51Sb（一种中 Z 元素）在其 Li (i = 1-3) 子壳吸收边缘的 40 个能量下的 X 射线质量衰减系数，覆盖了 4.0 以内的扩展能量区域。 keV–14.0 keV。本研究的目的是通过使用可调谐能量同步辐射，以更高的精度通过实验确定 51Sb 的关键 X 射线基本参数。根据目前测量的质量衰减系数，Li (i = 1–3) 子壳层光电离截面 ( σ Li P ) 已在 Li (i = 1–3) 边缘能量的 24 个能量处推导出通过使用实验推导出的 Li (i = 1-3) 边缘跳跃比，51Sb 覆盖了 4.150 keV-5.0 keV 区域。
