Abstract

The mechanism for the d(p,{\gamma})3He reaction in the region of ultralow proton-deuteron collision energies (6.67<E<12.67 keV) is investigated using a target of zirconium deuterides. 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 the LUNA collaboration with the target of gaseous deuterium.
