## 2-roton Raman spectra of superfluid 4He have been measured at T=0.65K under pressures from svp to P=20kg/cm\*. No intrinsic spectral width has been observed at all pressures. Contribution of phonons has been found in the lower energy region of the P-roton peak. Considering it, the experimental

We report measurements of the roton second sound velocity and absorption at high pressure and low temperature. The velocity measurements show the existence of a dip over a very small range of temperature. Comparing this to the absorption measurements, we show that this dip corresponds to a pure roto
