We experimentally observed interference effects in elastic x-ray scattering from gas-phase HCl in the vicinity of the Cl K edge. Comparison to theory identifies these effects as interference effects between non-resonant elastic Thomson scattering and resonant Raman scattering. The results indicate the non-resonant Thomson and resonant Raman contributions are of comparable strength. The measurements also exhibit strong polarization dependence, allowing an easy identification of the resonant and non-resonant contributions.
我们在氯 K 边附近的气相 HCl 的弹性 X 射线散射实验中观察到了干涉效应。与理论的比较将这些效应确定为非共振弹性汤姆逊散射和共振拉曼散射之间的干涉效应。结果表明，非共振汤姆逊和共振拉曼的贡献具有相当的强度。这些测量还表现出强烈的偏振依赖性，这使得很容易识别共振和非共振的贡献。
