The study of fusion reactions 
, 
, 
, 
, and 
at astrophysical energies is of interest for both basic and applied physics. These studied provide information on electron screening of nuclear reactions that provide important information on the role of electrons in reactions induced by deuterons, tritons, and nuclei of helium isotopes that proceed in reactors. The reaction was investigated at the pulsed plasma Hall accelerator (Tomsk) in the 
ion energy range 
keV (laboratory reference frame) with a step of 2 keV. The goal of this work was to determine experimentally the enhancement factor of the 
reaction and the electron screening potential 
using a TiD targets with Miller indices [111] and [100]. A strong impact of the target crystal structure on reaction enhancement factor was discovered. We believe that solid-state effects make the largest contribution to the behavior of the enhancement factor 
of the reaction as a function of energy. One of these effects is the particle channeling in crystal structures. An unexpected increase of the enhancement factors for the reaction in the energy range 
keV probably indicates the emergence of some new mechanism that increases the yield of the reaction with lowering energy.
