摘要：
The magnetic excitations of an antiferromagnetic spin-dimer system, (VO)DPO4.1/2D(2)O, are examined using inelastic neutron scattering technique. A dispersionless mode is found, consistent with our expectations for a dimer excitation. The intensity variation of the mode reveals a V4+-V4+ dimer separation of 4.43 Angstrom, almost 50% larger than the originally expected length. (C) 1998 Elsevier Science B.V. All rights reserved.
