We investigate the rare-earth polychalcogenide R<Subscript>2</Subscript>Te<Subscript>5</Subscript> (R=Nd, Sm and Gd) charge-density-wave (CDW) compounds by optical reflectivity measurements. We obtain the optical conductivity through Kramers-Kronig transformation of the reflectivity spectra. From the real part of the optical conductivity we...</subscript></subscript>
