用微分扰动角关联(DPAC)和微分扰动角分布(DPAD)方法来研究固体材料中的缺陷和辐射损伤的微观机理,是近几年来发展的“第三代”超精细相互作用研究,在国外开展得不少。 由于这类相互作用比较微弱,“捕捉”到缺陷的核探针占总数的比例很少,因此进行这种研究时,需要特别精确地获取数据及分析数据,对谱仪测谱的微分线性和时间分辨要求很高,这是与磁相互作用研究不同的一个特点。 The study of the microscopic mechanism of defects and radiation damage in solid materials by differential perturbation angle correlation (DPAC) and differential perturbation angle distribution (DPAD) is a “third generation” ultrafine interaction developed in recent years. Carry out a lot. Because of this relatively weak interaction, the percentage of nuclear probes that “trap” to defects is small, so this study requires very precise data acquisition and analysis of the differential linearity of the spectrometer spectra Time-resolved demanding, which is different from the magnetic interaction study of a feature.
