A complete 11th order calculation is carried out for the alternating Heisenberg chain. For $\\lambda=0.27$, relevant to the material $Cu(NO_3)_2.2.5D_2O$, we present detailed spectral weights for the two-triplet continuum and all bound states. We also examine variation of the relative weights of one and two-particle states with bond alternation from the dimerized to the uniform chain limit.","authors_text":"C.J. Hamer, R.R.P. Singh, W.
