Abstract
An attempt is made to analyze the dependence of the Raman scattering cross section or the absorption∕emission of electromagnetic waves by a Bose-Einstein condensate of magnons on their (magnons) density. Specifically, the intensities of one- and two-magnon transitions are compared and it is concluded that latter dominate in a Bose condensate. The salient features and possible role of the intermagnon interaction are discussed briefly.
