摘要：

The pressure dependence of the multiphonon excitations in superfluid 4He has been studied, using neutron inelastic scattering. High-resolution measurements have been made at 0,5 K over a wavevector range 0.6<Q<2.2 Å−1, at various pressures between 0 and 20 bars. The experimental data are presented and existing theoretical calculations are discussed.
