【摘要】：自康普顿散射提出以来,其理论研究和应用研究一直是国内外的热点。基于NaCl和KCl溶液的康普顿散射,通过一定的近似处理,从理论上分析适合这两种溶液的康普顿散射光子数与溶液浓度之间的关系表达式;然后,通过康普顿散射实验验证康普顿散射的理论和实验研究。为了从更微观的角度来把握NaCl和KCl溶液康普顿散射的机理,笔者立足于密度泛函理论对NaCl与KCl溶液的电子结构作了深入分析,得出结论:除质量密度、散射衰减因子以及溶液的浓度外,电子数密度和电子受到的束缚也对康普顿散射光子数有影响,其中,电子数密度是影响NaCl与KCl溶液康普顿散射光子数的主要因素。
[Abstract]:Since Compton scattering was put forward, its theoretical and applied research has been a hot topic at home and abroad. Compton scattering based on NaCl and KCl solution is treated by some approximation. The relationship between the Compton scattering photon number and the concentration of the solution is theoretically analyzed. Then, the relation between the number of Compton scattering photons and the concentration of the solution is analyzed. The theoretical and experimental studies of Compton scattering are verified by Compton scattering experiments. In order to understand the mechanism of Compton scattering in NaCl and KCl solutions from a more microscopic perspective, Based on the density functional theory, the electronic structure of NaCl and KCl solution is analyzed. It is concluded that, in addition to the mass density, the scattering attenuation factor and the concentration of the solution, The number of Compton scattering photons is also affected by the electron number density and the binding of electrons. The electron number density is the main factor affecting the Compton scattering photon number of NaCl and KCl solutions.
