• A theory of the cooperative Jahn-Teller effect is developed to elucidate a structural phase transition observed in the CsCuCl_3 crystal. This theory establishes the relationship between the local and the cooperative Jahn-Teller effect. We find that the helical alignment of Cl^- ions along the c-axis agrees with experimental data when the two Δ_6 modes of the phonons executed by the Cl^- ions contribute to the structutal phase transition.
