摘要：

Using a modified Lanczos scheme, we evaluate the ground state properties of a sixteen-site one-dimensional spin- 1/2 Heisenberg antiferromagnet. We consider the case with nearest-neighbor antiferromagnetic interactions and next-nearest-neighbor ferromagnetic interactions as well as anisotropy. Comparisons are made with other exact results in the appropriate regions of parameter space.
