Abstract:

Crystal fields split the free ion spectra of rare earths when such ions are incorporated in crystalline solids. A scanning spectrometer was used to obtain the crystal absorption spectra of neodymium in calcium tungstate in the region 11,400 to 19,600cm. From these spectra the energy levels are obtained and most of them are labeled with the irreducible representations of the SS4 point symmetry group of the crystal site that the neodymium ion occupies.
