摘要：

The crystal structure and the crystalline-electric-field splitting of the Er3+ 4f-shell in the high-T(c) superconductor ErBa2Cu3Ox (x = 6.95, 6.18) disordered with fast neutron irradiation has been investigated by elastic and inelastic neutron scattering techniques, respectively. The results yield evidence for the absence of a charge transfer between the planes and chains under disorder and point to the atomic displacements being the main radiation-induced defects in the CuO2 planes.
