Abstract
Radiation damage, which occurs in the beam of the electron microscope, has been studied in uranyl acetate stained crystals. Damage is observed in terms of the disappearance of higher orders of the electron diffraction pattern. In this study it has been found that the damage at very low specimen temperatures proceeds both more rapidly and to a greater final degree than is the case at room temperature.
摘要
在醋酸双氧铀染色的晶体中，对发生于电子显微镜束流中的辐射损伤进行了研究。根据电子衍射图案高阶条纹的消失来观察损伤情况。在本研究中发现，在极低的样品温度下，损伤比在室温下发生得更快，且最终程度更大。
