Microscopic calculation of the inclusive electron scattering structure function in O-16

Abstract

We calculate the charge form factor and the longitudinal structure function for ${}^{16}$O and compare with the available experimental data, up to a momentum transfer of 4 fm${}^{-1}$. The ground state correlations are generated using the coupled cluster [exp(S}] method, together with the realistic v-18 NN interaction and the Urbana IX three-nucleon interaction. Center-of-mass corrections are dealt with by adding a center-of-mass Hamiltonian to the usual internal Hamiltonian, and by means of a many-body expansion for the computation of the observables measured in the center-of-mass system.
