Abstract

Experimental results are presented that were obtained by measuring the astrophysical S factor for dd interaction at very low deuteron collision energies by using the liner-plasma technique. The experiment was performed at the high-current generator of the High-Current Electronics Institute (Tomsk, Russia). The values found for the S factor at the deuteron collision energies of 1.80, 2.06, and 2.27 keV are Sdd = 114 ± 68, 64 ± 30, and 53 ± 16 keV b, respectively. The corresponding dd cross sections obtained as the product of the barrier factor and the measured astrophysical S factor are σndd(Ecol = 1.80 keV) = (4.3 ± 2.6) × 10-33cm2, σndd(Ecol = 2.06 keV) = (9.8 ± 4.6) × 10-33cm2, and σndd(Ecol = 2.27 keV) = (2.1 ± 0.6) × 10-32cm2.
