Abstract
Emission spectra of intrinsic and impurity-trapped excitons and their side- bands have been measured in CsMnF 3 by a polarized time-resolved spectroscopy. From a biexcitonic decay of an emission an exciton- exciton interaction was found to be very small in contrast with those of MnF 2 and KMnF 3. Multimagnon sidebands have been assigned with the aid of calculation of magnon density of states.
