β decay of proton-rich nucleus 23Al and astrophysical consequences

We present the first study of the β decay of 23Al undertaken with pure samples. The study was motivated by nuclear astrophysics questions. Pure samples of 23Al were obtained from the momentum achromat recoil separator (MARS) of Texas A&M University, collected on a fast tape-transport system, and moved to a shielded location where β and β-γ coincidence measurements were made. We deduced β branch...

Core excitations in exotic nuclei

The role of core excitations in exotic nuclei is discussed in the framework of a microscopic cluster model. This cluster approach is complemented by the R-matrix theory to take account of the long-range part of the wave functions. We briefly describe the model, and present two recent examples: the neutron-rich nucleus B, described by a B+n structure, and the proton-rich nucleus Na, described by...

Relativistic Hartree-Bogoliubov and RPA description of exotic nuclear structure

A review of recent applications of the relativistic mean-field theory to the structure of exotic nuclei is presented. Models based on the relativistic mean-field approximation provide a microscopically consistent description of the nuclear many-body problem, not only in nuclei along the valley of β-stability, but also in exotic nuclei with extreme isospin values and close to the particle drip l...

Nuclear Astrophysics with Radioactive Nuclear Beams: Indirect Methods

The review describes a number of indirect methods in nuclear astrophysics using radioactive beams: Coulomb dissociation, transfer reactions (the ANC method), breakup of loosely bound nuclei at intermediate energies, the use other spectroscopic measurements, including -decay studies and the determination of resonance parameters. The examples chosen are drawn from the experiments the author was i...

Effective density dependent pairing forces in the T=1 and T=0 channels

The novel availability of exotic nuclei has spurred an immense revival of nuclear structure investigations [1]. Indeed nuclei close to the neutron or proton drip lines may exhibit very unusual features such as pronounced neutron or proton skins [2], and neutron halos [3]. Among many very interesting questions, nuclear pairing has again become on the forefront of theoretical interest. Indeed the...
