1. Nuclear symmetry energy and neutron-proton pair correlations in microscopic mean field theory
Abstract : A major task of nuclear structure theory is to develop an effective interaction that is capable to predict properties of nuclei under extreme conditions. In this thesis three different areas of effective interactions have been studied: i) the density dependence, which is of importance for the understanding of neutron stars and neutron rich nuclei; ii) the symmetry energy which governs the evolution of the binding energy with changing N/Z ratio; and iii) the neutron proton pairing energy.

3. Analysis of the Unbound Spectra of 12Li and 13Li
Abstract : The properties of unbound nuclei 12Li and 13Li are calculated within themultistep shell model in the complex energy plane by assuming that the spectraare determined by the motion of neutrons outside the 9Li core. It is foundthat in 12Li the ground state consists of an antibound 1/2+ state and thatonly this and a 1/2− and a 5/2+ excited states are physically meaningfulresonances. READ MORE

4. Multistep Shell Model in the Complex Energy Plane
Abstract : In this thesis the properties of unbound nuclei like 12,13Li are studiedby extending the multistep shell model to the complex energy plane. Thenuclei 12Li and 13Li are described starting from the one-particle states in 10Liand two-particle states in 11Li. The ground state of 12Li is found to be anantibound state. READ MORE
