✦ Synopsis

We calculate the dynamic structure factor of liquid helium on the basis of a new microscopic theory. The structure factor obtained from the present theory contains a delta-functional peak for the second sound at any temperature lower than the 2 -point. If the experimental precision in Brillouin scattering of laser-light become more acccurate than now, this delta-functional peak will be discovered.
