Neutron spectroscopic experiments performed for the high-Tc superconducting hole-doped RBa2Cu3Ox (R=rare earth; 6\_<x<7) and electron-doped R2\_xCexCuO4-~i (~\_x\_<0.2) compounds are discussed. In these systems the R ions are situated close to the superconducting CuO2 planes, thus the crystal-field
