1. 1. Bits and Pieces for the Nuclear Puzzle - Exploring light exotic nuclei with radioactive ion beams

   Författare :Ronja Thies; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ISOLDE; GSI; FAIR; R3B; Neutron-rich nuclei; Radioactive Beams;

   Sammanfattning : Atomic nuclei are a fascinating case of many-body systems governed by quantum behaviour. This fact and the complex nuclear interaction are reasons why there is not yet a complete theory describing all atomic nuclei. Both experimental and theoretical efforts are needed to change this situation. LÄS MER

3. 2. Probing single-particle and collective states in atomic nuclei with Coulomb excitation

   Författare :Douglas DiJulio; Kärnfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; reduced matrix elements; radioactive ion beams; Coulomb excitation; Fysicumarkivet A:2013:Di Julio; detector development;

   Sammanfattning : A series of experiments and developments, related to stable and radioactive isotopes, have been carried out. These studies have focused on measuring the low-lying excitations of spherical and deformed nuclei using electromagnetic (Coulomb) excitation and also on developments in detector technology for upcoming radioactive ion beams facilities.

4. 3. To fission or not to fission: 230Ac

   Författare :Anna Kawecka; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Heavy Elements; r-process; CERN; Actinides; Radioactive Beams; ISOLDE; Fission; ISS;

   Sammanfattning : Around half of the elements heavier than iron found in the Universe are believed to have been formed during the rapid neutron capture process (r-process). During the r-process, very neutron-rich nuclei are created through a series of neutron captures and β−-decay reactions. LÄS MER

5. 4. Spectroscopy of Stable and Radioactive Negative Ions

   Författare :Annie Ringvall-Moberg; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Atomic Physics; ISOLDE; CERN; Electron Correlation; Electron Affinity; Photodetachment; Negative Ions; Anions; Radioisotopes; Laser Photodetachment Spectroscopy; Resonance Ionization; Neutral Particle Detection; Wigner Threshold Law; Molecular Dissociation; RFQcb; DESIREE; Radiative Lifetimes;

   Sammanfattning : Negative ions are unique quantum systems which are of fundamental interest within the field of atomic physics due to the importance of the electron correlation in their creation, stability, and existence. Properties of these ions, such as the electron affinity, i.e. LÄS MER

7. 5. Effective Charges in Nuclei in the vicinity of 100Sn

   Författare :Andreas Ekström; Kärnfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The shell structure of atomic nuclei far from the line of beta-stability and the properties of the nucleon-nucleon interaction in exotic isotopes are not well known. The development of radioactive ion beams (RIBs) puts certain unexplored regions of the nuclear chart within reach of detailed experimental investigations. LÄS MER
