“…The obtained results of the studied reactions (1a) (1b) in the last decade [1][2][3][4][5][6][7][8][9][10], show the existence of an enhancement effect in the reaction of dd synthesis in deuteride metals, resulting from the presence of elec tron screening of deuterium nuclei. To verify the exist ence of this effect we have conducted experiments with beams of deuterons accelerated by a pulse Hall accelerator and using targets with deuterides of tita nium, zirconium and tantalum [8][9][10].…”

The article is devoted to the investigation of a pd reaction (p + d 3 He + γ(5.5 MeV)) under going in titanium deuteride in astrophysical collision energy region of protons and deuterons ranging from 5.3 to 10.5 keV. The experiments have been performed using the Hall NR TPU (Tomsk, Russia) pulsed plasma accelerator. The number of accelerated protons in 10 μs pulse was 5 × 10 14 at a repetition rate of 7 × 10 -2 Hz. Detection of 5.5 MeV gamma rays was carried out using eight detectors based on crystals of NaI(Tl) (100 × 100 × 400 mm) placed around the TiD target. For the first time, the dependencies between the astro physical S factor and the effective cross section of the pd reaction from proton-deuteron collision energy, and the potential electronic screening of the interacting protons and deuterons in titanium deuteride have been measured.
