Abstract
Inelastic neutron scattering study has revealed that along the a*-axis the energies of the longitudinal acoustic and the transverse acoustic phonon wi th polarized along the b*-axis are nearly equal. The similar relationship h as also been found for the phonon branches propagating along the b*-axis. T his strange feature may originate from the special structure of CuGeO3 that has CuO2 and GeO chains aligned along the c-axis and interacting very weak ly with each other.
