Research Abstract

(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.
