Temperature-dependent Brillouin scattering studies have been carried out onLa_{0.77}Ca_{0.23}MnO_3 across the paramagnetic insulator - ferromagnetic metal(I-M) transition. The spectra show a surface Rayleigh wave (SRW) and a highvelocity pseudo surface acoustic wave (HVPSAW) besides bulk acoustic waves(BAW). The Brillouin shifts associated with SRW and HVPSAW show blue-shifts,where as the frequencies of the BAW decrease below the I-M transitiontemperature (T_C) of 230 K. These results can be understood based on thetemperature dependence of the elastic constants. We also observe a central peakwhose width is maximum at T_C.Comment: 7 pages, 8 figure
