The electron-quasiparticle interaction (EQI) spectral function has been measured for DyNi2B2C in the normal state at low temperatures by means of point-contact spectroscopy (PCS). A low-frequency peak is found around eV similar to 5 meV. It becomes measurable at T-m* similar or equal to 15 K and grows in intensity with constant width as the temperature is lowered. We argue that this peak arises from the strong interaction of conduction electron with coupled crystal-electric-field-phonon excitations whose branches cross at low energy. The comparison with PC spectra for HoNi2B2C suggests that a similar peak also exists for this compound. The magnitude of the point-contact EQI parameter lambda(PC) for DyNi2B2C is estimated.
