大角度和小角度衍射研究都是在堆辐照石英玻璃上进行的。从大角度散射得到的径向分布曲线与西蒙的早期工作基本一致。用相对较低的快中子剂量辐照的样品的小角度散射显示出在最小角度处散射的显著增加。两个可能的原因，这种散射的建议。此外，所有辐照样本在整个小角度区域的散射普遍增加。这种散射，表现出很小的角度依赖性是由于照射后的样品内的密度波动增加。通过在1300°C下对玻璃进行退火，几乎完全去除了辐射诱导的散射。
Both large‐angle and small‐angle diffraction studies have been made on pile irradiated silica glass. The radial distribution curves obtained from the large‐angle scattering were in essential agreement with the earlier work of Simon. The small‐angle scattering from samples irradiated with a relatively low fast neutron dose showed a noticeable rise in the scattering at the smallest angles. Two possible causes of this scattering are suggested. In addition, all irradiated samples showed a general increase in the scattering over the entire small‐angle region. This scattering which showed little angular dependence was attributed to increased density fluctuations within the sample after irradiation. The irradiation induced scattering was almost completely removed by annealing the glass at 1300°C.
