1. Excursions Along the Drip Line
Sammanfattning : The drip lines are the outer boundaries of the chart of the nuclides, terminating the isobaric chains on both sides of the valley of .beta.-stability with respect to stability against particle emission. The neutron drip line is, at the moment, only experimentally accessible for the very lightest elements. LÄS MER
2. 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
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. Probing the Drip-Lines through Momentum Distributions
Sammanfattning : About a decade ago it was found that nuclei in the vicinity of the neutron drip-line under certain circumstances develop very extended valence neutron distributions, a phenomenon today known as halo states. The recent development of radioactive nuclear beams has provided us with a perfect tool for investigating these particular nuclei. LÄS MER
5. 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
