Abstract
A modified Gersch-Rodriguez formalism describing the leading Final State Effects in the high momentum transfer response of low concentration He-He mixtures is presented and discussed. The leading corrections to the Impulse Approximation are expressed in terms of the interatomic potentials and the semidiagonal two-body density matrices of both the mixture and its boson-boson approximation, in which the He atoms are replaced by bosons of the same mass and at the same partial density. Numerical calculations of the Final State Effects functions of He and He are finally presented and discussed.
