Abstract
We find that the three-body two-pion-exchange currents lead to an effect very similar to that of the two-body one-pion-exchange currents on the charge form factors of , , and . Most of this effect is, however, canceled by similar -meson-exchange currents. The four-body three-meson-exchange currents are of negligible importance for the α-particle charge form factor.
