摘要：
The ground state and spin excitations of a Heisenberg antiferromagnet on a triangular lattice with nearest- and next-nearest-neighbor interactions are investigated. Ground state has long-range order and becomes unstable near J2/J1 congruent-to 2/15. The possibility of spin liquid state is discussed.
