Title: Multiphoton boundary of the excitation spectrum in He II

Abstract

The behavior of the dynamic form factor in He II near the sound line ..omega..=up is obtained. General formulas are derived for the asymptotic forms of the imaginary parts of the Green's function at high frequencies and large momenta.
