  The coupled cluster method has been applied to the eigenvalue problem lattice
Hamiltonian QCD (without quarks) for SU(2) gauge fields in two space
dimensions.
  Using a recently presented new formulation and the truncation prescription of
Guo et al. we were able to compute the ground state and the lowest
$0^+$-glueball mass up to the sixth order of the coupled cluster expansion.
  The results show evidence for a ``scaling window'' (i.e. good convergence and
constance of dimensionless quantities) around $\beta=4/g^2 \approx 3$.
  A comparison of our results to those of other methods is presented.
