We report results of a Raman scattering study of superconducting YNi{sub 2}B{sub 2}C with {ital T}{sub {ital c}}=15.2 K. A redistribution of low-frequency light scattering intensity is observed in the temperature range 10--200 K. It is interpreted in terms of electron-hole excitations and their scattering due to impurities and phonons. The scattering rate is found to decrease linearly with temperature.
