Electron screening in lithium-induced nuclear reactions
Year: 2025
Type: article
Abstract: The electron screening effect was studied in the 1 H( 7 Li, α ) 4 He, 2 H( 6 Li, α ) 4 He, 2 H( 6 Li,p 0 ) 7 Li and 2 H( 6 Li,p 1 ) 7 Li nuclear reactions on thin Ti, thick Pd and thin amorphous carbon targets containing hydrogen and deuterium. In the first three reactions, we measured high electron screening potentials for all targets that are significantly above the theoretical upper limit given by the adiabatic model, but in the last reaction we did not detect any enhancement of the cross section due to electron screening. This is the first time that different screening potentials were measured for the p 0 and p 1 reaction channels.
