Abstract
Neutron spectroscopy has been used to study the crystal field excitati on spectra in high quality samples of RBa(2)Cu(4)O(8) high temperature superconductors, with R = Dy, Ho and Er. The samples were prepared un der high oxygen pressure. Analysis of the spectra included treatment o f the spin-orbit and Coulomb interactions, sad yielded crystal field p arameters which showed a high degree of consistency from one rare eart h to another.
