摘要：
Low-energy collective angular momentum states of the Tb3+ ions in Tb2Ti2O7 are classified according to the irreducible representations of the octahedral point group. Degeneracy lifting due to the exchange interaction is discussed. Diffuse neutron-scattering intensity patterns are calculated for each collective angular momentum state, and the ground state is inferred by comparing with experiment.
