The goal is to evaluate the core approximation formula for the groundstate energy density of a 1+1-dimensional Heisenberg antiferromagnet, based upon a single-state truncation procedure out to range-6 and see how well the basic cluster expansion converges and then, how it can be accelerated using type-II Pade approximants.
