| 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: | The compton scattering of solution is a very meaningful aspect. On the basis of the Compton scattering of NaCl and KCl solution, we analyzed the relation expression between the Compton scattering photon number and the concentration of the solutions in theory by processing certain rational approximation, and then verified it through Compton scattering experiments. In order to grasp the micro-mechanism of Compton scattering of NaCl and KCl solution, we deeply analyzed the electronic structure of NaCl and KCl solutions according to the density functional theory. It is concluded that the factors influencing the Compton scattering photon number include electron number density, electron bound of scatterer, mass density, concentration of solutions and scattering attenuation coefficient, among which electron number density is the main factor. |
