Query: Study of the d(p,{\gamma})3He Reaction at Ultralow Energies using a
  Zirconium Deuteride Target   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.
