Investigation of the D(3He, p)4He Reaction in the Astrophysical Energy Region of 18–30 keV
The D( 3 He, p ) 4 He reaction is first investigated in a solid target of deuterated zirconium (ZrD) in the 3 He + ion energy range E He = 18–30 ( E = 7.2−12.0keV keV in the center-of-mass system) with a step of 2 keV. The electron screening potential U e = (617.8 ± 154.7) eV and the D( 3 He, p ) 4...

He 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(
