摘要：

This paper reports the first neutron scattering measurements on spin waves in a linear-chain antiferromagnet. Measurements were made on CsMnCl3 center dot 2D(2)O and clearly indicate a large directional anisotropy of the spin coupling. The dominant exchange occurs along chains extending in the a direction, J(1)= -0.304 +/- 0.003 meV. The exchange parameters in the b and c directions were measured in the combinative form J(2)+J(3)=-0.0021 +/- 0.0004 meV. Short-wavelength excitations along the chain direction persist even at 2 T-N.
