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.

用液体和LI靶标测量 ^6Li+ D反应，用于25至75 KEV之间的入射能。对于液体和固体靶标，分别将6Li（d，。）4HE反应的筛选势（US）分别推导为US = 488 +/- 40和395 +/- 40 eV。还测量了我们的温度依赖性，并表明我们随着温度的升高而降低。结果的解释方式是Li+离子还可以在电子筛选中有助于液体LI的筛选。此外，我们已经成功地在液体LI中产生了超声波声。可能会强烈影响反应速率的新环境已经开发出来。
