The paper is devoted to study electron screening effect influence on the rate of d (d, n) 3 He reaction in the ultralow deuteron collision energy range in the deuterated polyethylene (CD 2 ), frozen heavy water (D 2 O) and deuterated metals (ZrD 2 and TiD 2 ). The ZrD 2 and TiD 2 targets were fabricated via magnetron sputtering of titanium and zirconium in gas (deuterium) environment. The experiments have been carried out using high-current plasma pulsed accelerator with forming of inverse Z pinch (HCEI RAS, Russia) and pulsed Hall plasma accelerator (NPI at TPU, Russia). The detection of neutrons with energy of 2.5 MeV from dd reaction was done with plastic scintillation spectrometers. As a result of the experiments the energy dependences of astrophysical S factor for the dd reaction in the deuteron collision energy range of 2-7 keV and the values of the electron screening potential U e of interacting deuterons have been measured for the indicated above target: U e (CD 2 ) 40 eV; U e (D 2 O) 26 eV; U e (ZrD 2 ) = 157 ± 43 eV; U e (TiD 2 ) = 125 ± 34 eV. The value of astrophysical S factor, corresponding to the deuteron collision energy equal to zero, in the experiments with D 2 O target is found: S b (0) = 58.6 ± 3.6 keV b. The paper compares our results with other available published experimental and calculated data.

The temperature dependence of the enhancement factor for the dd reaction proceeding in TiD 2 and ZrD 2 is investigated. The experiments were carried out at the Hall pulsed ion accelerator (INP, Polytechnical University, Tomsk, Russia) in the deuteron energy interval 7.0 ÷ 12.0 keV and at temperatures ranging from 20 to 200 • C. The values obtained for the electron screening potentials indicate that the dd-reaction enhancement factor does not depend on the target temperature in the range of 20 ÷ 200 • C. This result contradicts the conclusions drawn by the LUNA Collaboration from their work.The investigation has been performed at the Dzhelepov Laboratory of Nuclear Problems, JINR.
