Study of the d(p,γ)3He Reaction at Ultralow Energies using a Zirconium Deuteride Target

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 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.

Nanogranular MgB2 thin films on SiC buffered Si substrates prepared by in-situ method

MgB2 thin films were deposited on SiC buffered Si substrates by sequential electron beam evaporation of B-Mg bilayer followed by in-situ annealing. The application of a SiC buffer layer enables the maximum annealing temperature of 830 C. The Transmission Electron Microscopy analysis confirms the growth of a nanogranular MgB2 film and the presence of a Mg2Si compound at the surface of the film. The 150-200 nm thick films show a maximum zero resistance critical temperature TC0 above 37 K and a critical current density JC ~ 106 A/cm2 at 11K.
