Abstract
The electric form factor of the pseudoscalar meson (generic pion) is calculated in quenched lattice quantum chromodynamics with SU(2) color using the Wilson formulation for fermions. Charge radii are calculated for different values of the hopping parameter. It is observed that heavier quarks have distributions of smaller radius. The results are compared with a previous calculation which used the staggered fermion scheme.
