| Abstract: | Emission spectra of intrinsic and impurity-trapped excitons and their side- bands have been measured in CsMnF3 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 MnF2 and KMnF3. Multimagnon sidebands have been assigned with the aid of calculation of magnon density of states. |
