Further Series Studies of the Spin-1/2 Heisenberg Antiferromagnet at   T=0: Magnon Dispersion and Structure Factors
  We have extended our previous series studies of quantum antiferromagnets at zero temperature by computing the one-magnon dispersion curves and various structure factors for the linear chain, square and simple cubic lattices. Many of these results are new; others are a substantial extension of previous work. These results are directly comparable with neutron scattering experiments and we make such comparisons where possible.
