N2 - Temperature and magnetic field dependent polarized Brillouin spectra of CuGeO_3 are reported. In addition to a bound singlet state at 30 cm^(-1), a new feature has been observed at 18 cm^(-1). This feature is interpreted in terms of a novel three-magnon light scattering process between excited triplet states.
