Abstract
The D(3He, p)4He reaction is first investigated in a solid
target of deuterated zirconium (ZrD) in the 3He+ ion energy range
keV (E=7.212.0 keV in the center-of-mass
system) with a step of 2 keV. The electron screening potential
eV and the D(3He, p)4He reaction enhancement factors
are experimentally determined in the given energy range. The measured electron
screening potential is six times higher than in gaseous targets. This
can be due to the ZrD lattice effects, which have not been studied either
theoretically or experimentally so far. The D(3He, p)4He reaction has
been investigated at the pulsed plasma Hall accelerator (Tomsk).
