Abstract
A particular quasi-one-dimensional Heisenberg antiferromagnet, which falls into a large and well-known class of models with simple dimerized ground states, is shown to have some especially appealing properties. For S=1/2 spins, all excited states are strictly localized, and may be identified with the states of collections of finite, open, S=1 chains.Keywords
