Abstract The effective light-cone Hamiltonian is extended to include the SU(3) flavor mixing interaction besides the confining potential. Solving the coupled J=0 mass eigen equations for the up, down, and strange quark components numerically, the masses of π0 and η, their radial wave functions, and rms radii are obtained in agreement with the experimental data.
