Abstract
We present a study of the pseudoscalar and vector meson form factors, calculated using the fat-link irrelevant clover (FLIC) action in the framework of quenched lattice QCD. Of particular interest is the determination of a negative quadrupole moment, indicating that the rho meson is not spherically symmetric.
