摘要：

We report measurements of S(Q, omega) of liquid He-4 covering the wave vector range from 3 to 17 angstrom-1 at T = 2.5 K and from 3 to 10 angstrom-1 at 1.4 K. Clear oscillations in both the width and position of the recoil peak are observed up to 12 angstrom-1 and can be attributed to coherent and final state effects. The observed shape of S(Q, omega) is well described by a recent expression by Glyde.
