摘要：

Inelastic neutron scattering has been employed to study the crystalline electric field (CEF) interaction in the high-T(c) superconductor YbBa2Cu3O7. The observed energy spectra exhibit three well defined CEF transitions at 88.5, 92.8 and 98.5 meV which completely determine the CEF splitting of the ground-state J-multiplet. A set of CEF parameters is derived which excellently reproduce the neutron spectroscopic data as well as the thermodynamic magnetic properties.
