The antiferromagnetic (AF) compound BaCu2Si2O7is studied by magnetic susceptibility and neutron-scattering techniques. The observed behavior is dominated by the presence of loosely coupled S=1/2 chains with the intrachain AF exchange constant J≈ 24.1 meV. Long-range Néel ordering is observed below TN=9.2 K. The results are discussed within the framework of the mean-field RPA model for weakly interacting quantum spin chains.
