Nucleus-Nucleus Interaction and Nuclear Saturation Property: Microscopic Study of 16O+16O Interaction by New Effective Nuclear Force

Abstract

By taking the 16O+16O system as an example, the property of nucleus-nucleus interaction is investigated by the use of resonating group method. Special attention is paid to the nuclear saturation property which is satisfied in all the interaction region from compact 32-nucleon configuration to two separated 16O nuclei. A new kind of effective nuclear force with a repulsive three-body interaction is introduced in order to take account of density dependent effects in relation to the saturation property. A kind of core in the inner region and a weak attraction in the intermediate region are discussed quantitatively for the 16O+16O interaction.
