Abstract: | It is shown that the singlet exciton spectrum in the crystal is coupled with that of the two-particle excitations (singlet, triplet excitons, magnons, triplet exciton-magnon). Splitting on the excitation spectrum occurs when the composite energy of the two-particle excitations is close to that of the singlet exciton. |
