摘要：
A model of electron screening of the proton and the Li atom in a solid target is presented in the frame of the density-functional theory. A fit of the enhancement factor is given for the astrophysical energy range. Deduced U-0 electron potential values are lower than the experimental ones. Possible causes of experimental uncertainties are finally discussed.
