摘要：

Temperature and magnetic field dependent polarized Brillouin spectra of CuGeO3 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 tripler states.
