Abstract
-
In an attempt to understand the success of Dirac phenomenology, Professors Celenza and Shakin proposed the so-called Relativistic-Brueckner-Hartree-Fock (RBHF) theory (Ref.5) which is characterized as having no free parameters other than those introduced in fitting free-space nucleon-nucleon scattering data.;A natural extension of the relativistic analysis of Ref. 5 lies in the study of the structure of finite nuclei. To avoid the formidable task of calculating relativistic Brueckner reaction matrices for a finite system, we use an effective interaction constructed for use in a Dirac-Hartree-Fock Calculation. This interaction reproduces, rather accurately, the nucleon self-energy in nuclear matter, the Migdal parameters and the saturation curves obtained via RBHF calculations.;We used this effective interaction in Dirac-Hartree-Fock calculations of the structure of the finite nuclei, {dollar}\sp{16}{dollar}O and {dollar}\sp{lcub}40{rcub}{dollar}Ca. We performed these calculations in momentum space and maintained translational invariance in our analysis. We have calculated the binding energies, nucleon energy levels, wave functions and the charge distributions for {dollar}\sp{16}{dollar}O and {dollar}\sp{lcub}40{rcub}{dollar}Ca. We find a good representation of the charge density of these nuclei and some degree of underbinding, which, in part, reflects the underbinding of nuclear matter for the one-boson-exchange potential (OBEP) whose reaction matrices are simulated by our effective interaction.
