Large electron screening effect in different environments

Electron screening effect was studied on different hydrogen containing targets with the 7Li, 11B and 19F ion beams. Results show large electron screening potentials strongly dependent on the proton number Z of the projectile. The largest ever measured screening potential with the value about a factor of 50 above the calculations from the model in adiabatic limit was observed in the graphite target containing hydrogen as an impurity.
