Study of the d(p, γ)~3He reaction at ultralow energies using a zirconium deuteride target

摘要

The mechanism for the d(p, γ)~3He reaction in the region of ultralow proton-deuteron collision energies (6.67 ＜ E ＜ 12.67 keV) is investigated using a target of zirconium deuteride. The experiment was carried out in the proton beam from the high-current pulsed Hall accelerator. Dependences of the astrophysical S-factor and the effective pd reaction cross section on the proton-deuteron collision energy are measured. The results are compared with the available literature data. The results of this work agree with the experimental results obtained by the LUNA collaboration with the target of gaseous deuterium.
