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.

^6Li+ D反应是用液态和固态Li靶测量的，入射能量在25 ~ 75 keV之间。6Li（d，.）4 He反应在液态和固态靶下的能量分别为Us=488+/-40和395+/-40 eV。还测量了Us的温度依赖性，并且显示Us随着温度的升高而减小。结果被定性地解释在这样一种方式，Li+离子可以有助于屏蔽在液体锂除了电子屏蔽。此外，我们已经成功地产生超声波空化液体锂;一个新的环境，可能会影响反应速率强烈已经开发。
