Approach to the asymptotic limit in inclusive scattering of neutrons from quantum liquids

We study the approach to the asymptotic limit in inclusive scattering in case the interaction between the constituents possesses a hard core. An extensive discussion is given of leading contributions to the linear response and of their dependence on various input components. The theory is applied to liquid ⁴He at T=1.2° K, q=10 A&#778^-1. .AE
