O108400100011 COMMENT -By authors. In this experiment, the difficulty is to O108400100012 determine the number of target deuterons in the D+D O108400100013 reaction. Since, the deuterons are accumulated in metalO108400100014 plate during the deuteron bombardment, the number of O108400100015 target deuterons changes. O108400100016 DETECTOR (TELES,SIBAR,SIBAR) A del'ta E-E counter telescope O108400100017 consisting of 50-mum and 200-mum thick Si-surface O108400100018 barrier detector was employed.
