1. Neutron Halo Nuclei
Sammanfattning : In light nuclei close to the neutron drip-line a spatially extended neutron distribution, the neutron, halo occurs. This is due to the relatively small binding energy of the last neutrons which makes possible quantum mechanical tunnelling of the last neutron(s) far away from the nuclear core. LÄS MER
2. Molecular observations of obscured galaxy nuclei
Sammanfattning : It is becoming evident that some (ultra)luminous infrared galaxies ((U)LIRGs) contain compact obscured nuclei (CONs) where luminosities in excess of 10^9 L☉ emerge from inside dusty regions smaller than 100 pc in diameter. Due to the obscured nature of these objects, their inner regions are hidden from examination using optical or infrared lines. LÄS MER
3. Exciting Neutron-rich Nuclei
Sammanfattning : Atoms are the building blocks which make up our world. Their stability depends on the atomic nucleus, consisting of protons and neutrons. Nuclei are complex many-body quantum mechanical systems governed by the nucleon-nucleon interaction. LÄS MER
4. Necked-in Superdeformed Nuclei
Sammanfattning : Superdeformation, i.e. elongated shapes with the longest axis approximately twice as long as the shorter axes, has provided many new insights in nuclear structure. In this dissertation the possibility of forming superdeformed states related to two connected spheres, having a more or less pronounced neck, is investigated. LÄS MER
5. Mirror Nuclei - Isospin Symmetry Breaking in the Mass A=35 and A=51 Mirror Nuclei
Sammanfattning : High-spin states in the A=35 mirror nuclei 35Ar and 35Cl and A=51 mirror nuclei 51Fe and 51Mn were populated using fusion-evaporation reactions. The gamma rays were detected in the powerful Ge arrays Gammasphere and GASP, respectively, which operated in conjunction with ancillary detectors for evaporated particles. LÄS MER
