摘要：

We present results of reflectivity measurements with E parallel to c and E perpendicular to c on NdBa2Cu3Ox (Nd123) single crystals close to full oxygen doping. Along the c-axis the optical conductivity sigma(1)(c) shows a well developed absorption band around 450 cm(-1) at, all temperatures. The in-plane optical properties are dominated by crystal-field excitations at lour energies, a prominent step at 400 cm(-1) and a weaker feature between 500 - 550 cm(-1). A comparison of sigma(1)(c) and the in-plane scattering rate Gamma(ab)(omega) with neutron scattering derived spin susceptibility spectra suggests that the in-plane and out-of-plane anomalies are caused by the same mechanism, probably electron-spin scattering.
