System analytical studies on ground state properties of neutron-rich nuclides in the nuclear mass region A ≅ 100
Description
In this thesis only nuclei with even proton and even neutron number have been studied. This constraint allows to use a for the description of excitation spectra very successful model, the interacting boson model (IBM) and to combine this with the density functional method. From the obtained Hamiltonian via an energy-density functional an effective potential is constructed which can be applied in the framework of the density-functional method in order to calculate ground state energies and densities. From the density distributions radii and values for the static deformation are determined. As further ground state property the separation energy for two neutrons is studied. (orig./HSI)
Abstract (German)
In dieser Arbeit sind nur Kerne mit gerader Protonen- und gerader Neutronenzahl untersucht worden. Diese Einschraenkung erlaubt es, ein fuer die Beschreibung von Anregungsspektren sehr erfolgreiches Modell, das Interacting Boson Model (IBM), zu verwenden und dies mit der Dichtefunktionalmethode zu kombinieren. Aus dem gewonnenen Hamiltonoperator wird ueber ein Energie-Dichtefunktional ein effektives Potential konstruiert, das im Rahmen der Dichtefunktionalmethode verwendet werden kann, um Grundzustandsenergien und -dichten zu berechnen. Aus den Dichteverteilungen werden Radien und Werte fuer die statische Deformation ermittelt. Als weitere Grundzustandseigenschaft wird die Separationsenergie fuer zwei Neutronen untersucht.
