摘要: 本文计算了在没有外电场和外加静电场情况下,能以Debye-Hückel方程描写其电荷输运的系统对光束、中子束和电子束的散射。所引起的是准弹性散射(瑞利散射)。在没有外电场情况下,瑞利散射的谱分布是两个峰宽不同而位置重迭的中心峰,且峰形不对称;外加静电场将引起瑞利峰宽度和位置的变动。本文并讨论了观察上述现象的可能性。

QUASI-ELASTIC SCATTERING OF LIGHT, NEUTRONS AND ELECTRONS FOR AN IONIC CONDUCTOR GOVERNED BY THE DEBYE-HüCKEL EQUATION

Abstract: An analytical treatment is given for the scattering of light, neutron and electron beams in the presence and absence of an external applied electro-static field by a system for which the charge transport can be described by the D-H equation. The resulting scatterings are shown to be quasi-elastic, i.e., Rayleigh scattering. When there is no external field, the spectral distribution of the Rayleigll scattering consists of two superposed central peaks of different widths, their shapes being assymmetric. The application of an external static electric field would give rise to variation of width and location of these Rayleigh peaks. The possibility of observing the above mentioned phenomena is also discussed.
