Abstract
We have observed one-particle, inelastic, polarized light scattering from low-lying excitons and magnons in single-crystal cobalt fluoride (Co) at 2°K. Because of the orbital nature of these excitations, the cross sections (- /sr) are much larger than for one-magnon scattering in the other case, which has been measured (Fe, ∼ /sr). Our measured cross sections are in good agreement with a recent calculation by Ishikawa and Moriya.
