Ground state correlations and mean-field in ${}^{16}$O: Part II

Abstract

We continue the investigations of the ${}^{16}$O ground state using the coupled-cluster expansion [$\exp (\mathbf{S})$] method with realistic nuclear interaction. In this stage of the project, we take into account the three nucleon interaction, and examine in some detail the definition of the internal Hamiltonian, thus trying to correct for the center-of-mass motion. We show that this may result in a better separation of the internal and center-of-mass degrees of freedom in the many-body nuclear wave function. The resulting ground state wave function is used to calculate the "theoretical" charge form factor and charge density. Using the "theoretical" charge density, we generate the charge form factor in the DWBA picture, which is then compared with the available experimental data. The longitudinal response function in inclusive electron scattering for ${}^{16}$O is also computed.
