| Research Abstract |
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.
