摘要：

The recent observation of a quite intriguing magnetic susceptibility in CuGeO3 below T-SP = 14.3K, strongly suggested that this copper oxide could be the first inorganic compound belonging to the family of spin-Peierls systems. Our neutron investigations confirmed the occurrence of a crystalline distortion below T-SP, corroborated by the appearance of superlattice peaks that are indexed with a wave vector k(SP) = (1/2,1,1/2). Inelastic neutron scattering experiments have also been performed; we present our results showing the presence of a gap in the spin dynamics.
