LiCl溶液康普顿散射的影响因素研究

Analysis of Factors Impacting LiCl Solution Compton Scattering

基于康普顿散射理论对LiCl溶液康普顿散射中的非相干散射衰减因子进行了分析,采用一定近似处理得出了符合LiCl溶液康普顿散射相对光子数与浓度关系的表达式,并进行了实验验证。然后立足于密度泛函理论,从微观角度对LiCl溶液的康普顿散射进行了深入分析,得到了LiCl溶液中Li+、Cl-的水合离子的电子结构,分析了电子数密度和电子受到的束缚对康普顿散射的影响。结果表明,除质量密度、散射衰减因子以及溶液的浓度对康普顿散射相对光子数有影响外,电子数密度和电子受到的束缚也对康普顿散射相对光子数有影响。

Based on Compton scattering theory , the incoherent scattering attenuation coefficient on the scattering of LiCl solution was discussed .By using some approxima‐tions ,the expressions of Compton scattering of LiCl solution were obtained ,and they are in agreement with the experiments .Then based on the density functional theory , the Compton scattering of LiCl solution was discussed from the microcosmic .The elec‐tronic structures of Li^＋ and Cl^- hydration were obtained in LiCl solution .And the fac‐tors ,electron number density and electron bound strength ,impacting LiCl solution Compton scattering photon relative counts were analyzed .The results show that the fac‐tors include the electron number density and the electron bound strength ,besides the mass density ,attenuation coefficient and solution concentration .
