Outline of Final Research Achievements

A target system has been developed to produce liquid Li cavitation. Charged particle spectra were measuerd from the D(d,p)T reaction in liquid Li irradiated by a 60-keV deuteron beam. Measurements were performed under the conditions; beam ON and OFF with ultrasonic operation ON and OFF. In the spectrum at the time of beam off, an effect which cannot be ignored with respect to ON/OFF of the ultrasonic operation appeared. By subtracting the spectrum at OFF of ultrasonic operation from the spectrum at ultrasonic ON, we found a bump structure near 2 MeV. Currently, this bump structure is presumed to be due to protons from the D(d,p)T reaction caused by ultrasonic cavitation at the time of beam off.
