摘要：

Using a reduced Lanczos scheme, we evaluate the ground-state energy and all two-particle correlation functions of a one-dimensional Heisenberg spin-1/2 model with antiferromagnetic nearest-neighbor and antiferomagnetic next-nearest-neighbor interactions. The effects of anisotropy are also considered.
