【摘要】：自康普頓散射提出以來(lái),其理論研究和應(yīng)用研究一直是國(guó)內(nèi)外的熱點(diǎn)。基于NaCl和KCl溶液的康普頓散射,通過一定的近似處理,從理論上分析適合這兩種溶液的康普頓散射光子數(shù)與溶液濃度之間的關(guān)系表達(dá)式;然后,通過康普頓散射實(shí)驗(yàn)驗(yàn)證康普頓散射的理論和實(shí)驗(yàn)研究。為了從更微觀的角度來(lái)把握NaCl和KCl溶液康普頓散射的機(jī)理,筆者立足于密度泛函理論對(duì)NaCl與KCl溶液的電子結(jié)構(gòu)作了深入分析,得出結(jié)論:除質(zhì)量密度、散射衰減因子以及溶液的濃度外,電子數(shù)密度和電子受到的束縛也對(duì)康普頓散射光子數(shù)有影響,其中,電子數(shù)密度是影響NaCl與KCl溶液康普頓散射光子數(shù)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.
