(1) A dynamical screening effect induced by deuteron beam bombardment was studied for alpha-decay nucleus 147Sm in a metal Sm plate. An upper limit of the screening energy was deduced to be 19.3 keV.(2) A high temperature dueterium plasma was generated by irradiating a deuteron beam on liquid Li under ultrasonic operation. The temperature of the deuteron plasma in ultrasonic cavitation is deduced to be more than 10E6 K.(3) Cooperaion colliding d+d reaction, which is unique for melecular deuteron beam bombardment, was found for the first time. The screening energy of the d+d reaction in liquid In and Sn was measured using this reaction.

(1)研究了金属Sm板中氘核束轰击α衰变核147Sm的动态屏蔽效应。推导出屏蔽能量的上限为19.3 keV。(2)在超声操作下用氘核束照射液态锂产生高温重氢等离子体。推测超声波空化中氘核等离子体的温度超过10E6K。(3)首次发现了分子氘束轰击所特有的合作碰撞d+d反应。使用该反应测量了液体 In 和 Sn 中 d+d 反应的屏蔽能。
