Abstract

The results of the measurements of the astrophysical S -factor and cross-sections of the reaction dd → ^3He+ n in the deuteron energy collision range of 2.3-6.2keV are presented. The experiment was carried out at the high-current deuteron beam of the Hall pulsed accelerator (FSSI “Nuclear Physics Institute”, Tomsk). Deuterated polyethylene (CD₂) targets and frozen heavy water (D₂O) were used. Neutrons were detected by eight plastic scintillation counters ( 375×100×100 mm^3) located around the target. The results obtained in the present work substantially differ from the results of the experiments conducted with the use of deuterium saturated metal targets (TiD, TaD, ZrD, PtD). Within statistical errors of measurements there is no discrepancy between the present results and the results of the experiments performed with the heavy-water targets and filled with gaseous-deuterium targets.
