Abstract:The probabilities of the two-photon absorption by a biexciton in the ground and the first vibrational states in CuBr and the probability of the two-photon Raman scattering with the participation of the ground and the first vibrational states of the biexciton as intermediate states are calculated by perturbation theory method. Supposing that a Lorentzian distribution of frequencies w( of the exciting light and a Lorentzian shape of the emission lines of the exciton occur, the shape of the emission line at diffe… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
