In this paper, we prove that the even solution of the mean field equation Δu=λ(1eu)Δu=λ(1-e^u) on S2S^2 must be axially symmetric when 4<λ84<λ\leq 8. In particular, zero is the only even solution for λ=6λ=6. This implies the rigidity of Hawking mass for stable constant mean curvature(CMC) sphere with even symmetry.
