Investigation of the mechanism on nuclear excitation by electron transition and its application

为了研究电子跃迁激发（NEET）机制及其应用，我们在^ Au和^ Ir上精确地观察到<197><193>了NEET。为NEET实验研制了新型快速硅雪崩二极管（Si-AD）阵列探测器和无死区时间谱系统。该系统提高了对NEET事件的处理效率。根据实验结果，我们证实了我们的NEET模型依赖于入射X射线能量。

We have precisely observed nuclear excitation by electron transition (NEET) on ^<197>Au and ^<193>Ir to investigate the NEET mechanism and its application. New fast silicon avalanche diode (Si-AD) array detectors and a time spectroscopy system without a dead time region were developed for the NEET experiments. The system improved the efficiency for taking the NEET events. From the experimental results, we then confirmed our NEET model depending on the incident X-ray energy.
