我们对镶嵌晶体的共振核布拉格散射进行了时间分辨同步辐射测量。它已被证明，镶嵌结构的[sup 57]Fe[sub 2]O[sub 3]晶体大大减少加速效应相比，完美的晶体，与理论预测一致。此外，我们研究了粉末[sup 57]Fe[sub 2]O[sub 3]过滤器对共振光束的时间结构的影响，并讨论了这些结果与时域散射光谱的高分辨率能量分析仪的发展有关。
We have made time-resolved synchrotron radiation measurements of resonant nuclear Bragg scattering from a mosaic crystal. It has been shown that the mosaic structure of the [sup 57]Fe[sub 2]O[sub 3] crystal substantially reduces speed-up effects compared to that for perfect crystals, in agreement with theoretical predictions. In addition, we have investigated the effects of a powdered [sup 57]Fe[sub 2]O[sub 3] filter on the time structure of a resonant beam and we discuss these results in relation to the development of ultrahigh resolution energy analyzers for time-domain scattering spectroscopy.
