| Research Abstract |
The ^6Li+ D reaction was measured with liquid and solid Li target for incident energies between 25 and 75 keV. The screening potential (Us)for the 6Li(d,.)4He reaction was deduced as Us=488+/-40 and 395+/-40 eV, respectively for liquid and solid target. The temperature dependence of Us was also measured and it is shown that Us decreases as the temperature increases. The results are qualitatively interpreted in such a way that Li+ ions can contribute to the screening in liquid Li in addition to the electronic screening. Moreover, we have succeeded to produce ultrasonic acoustic cavitations in liquid Li ; a new environment which may affect the reaction rates strongly has been developed.
