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. Effective Field Theory and One-proton Halo Nuclei
Sammanfattning : In this thesis we present formalism for treating one-proton halo nuclei in effective field theory. Halo nuclei are loosely bound systems consisting of a core plus valence nucleon(s). In so called Halo, or Cluster, effective field theory, the core of the halo nucleus is treated as a structureless, effective degree-of-freedom. LÄS MER
3. On the Few-Body Character of Light Exotic Nuclei - Analytical Studies of Electromagnetic Processes Involving Loosely Bound Systems
Sammanfattning : The few-body character of loosely bound nuclei along the drip lines is studied within an analytical approach. It is argued that the clusterization of these systems leads to a modification of the normal phase space distribution of fragment momenta in breakup reactions. LÄS MER
4. Bound states and resonances in three-body system
Sammanfattning : The quantum three-body problem plays an important role in different branches of the modern physics. In the nuclear, atomic and molecular physics there exist a number of systems whose behaviour is naturally described in this framework. LÄS MER
5. Cluster Effective Field Theory
Sammanfattning : Halo nuclei are loosely bound systems consisting of a core plus valence nucleon(s). In so called Halo, or Cluster, effective field theory, the core of the halo nucleus is treated as an effective degree-of-freedom without internal structure. LÄS MER
