The theory, developed as a natural extension of the Gersch-Rodriguez formalism, incorporates the Fermi statistics explicitly through a new additive term which depends on the semidiagonal two-body density matrix. The use of a realistic momentum distribution, calculated using the diffusion Monte Carlo method, and the inclusion of this additive correction allows for good agreement with available deep-inelastic neutron scattering data.4 p.application/pdfeng(c) American Physical Society, 2004Liquids quànticsEstadística quànticaQuantum liquidsQuantum statisticsinfo:eu-repo/semantics/article515131info:eu-repo/semantics/openAccess
