| Outline of Final Research Achievements |
We have developed a system of stopped unstable nucleus target for studies of excited states of unstable nuclei and low-energy nuclear reactions that are relevant to nuclear astrophysics. We have successfully demonstrated the achievability of those measurements.
Implanted stable nucleus targets were produced by bombarding a deuteron beam on metallic foils in 1 mm diameter. By irradiating a higher energy deuteron beam on the target, deuteron-deuteron fusion reaction has been successfully detected.
Next unstable beryllium nuclei were produced by bombarding a proton beam on lithium target in 1 mm diameter. By irradiating a deuteron beam on the target, outgoing protons produced by the nuclear reaction with an beryllium nucleus and a deuteron has been successfully identified. This is the first successful measurement of nuclear reactions with stopped unstable nucleus target in a small area.
