I summarize recent observational progress on measurement of the elemental
abundances of early generation stars, which have recorded
(and preserved) the first episodes of nucleosynthesis in the Galaxy.
I discuss two major recent surveys, one just completed, one just beginning.
The first, the Hamburg/ESO R-process-Enhanced Star (HERES) survey has
obtained ``snapshot'' high-resolution...

A variety of astrophysical processes contribute to the synthesis of heavier
elements in nature. The characteristics of the processes are governed by the
astrophysical environment and details of the nuclear processes involved.
Experiments performed at ISOLDE have played a central role in developing
understanding of these processes. In this presentation, highlights to be discussed...

The first evidence of the occurrence of nucleosynthesis in stars was provided in the
1950s by the detection of the unstable heavy element technetium in the atmospheres
of stars on the Asymptotic Giant Branch (AGB), a late evolutionary phase of stars of
low mass. Technetium can be produced by slow neutron captures (the s process) and
thus its detection requires that neutron source...

As pointed out by Willie Fowler, the goals of nuclear astrophysics are to understand
the mechanism of Nucleosynthesis and the process of energy generation in stellar
environments. While a good deal is now known on what occurs in quiescent stellar
burning, much less is known about pathways to heavy element production in explosive
scenario. The former is largely dominated by nuclear...

In the last decades considerable effort in experimental nuclear astrophysics, stellar
modelling, and observations led to an improved understanding of various
nucleosynthesis scenarios. This is particularly true for the main s process in
low-mass AGB stars, which is largely responsible for the production of about half of
the elemental abundances in the mass range 90 ≤ A ≤ 209. The weak s...

Physics at the proton and neutron drip lines
Invited oral contribution
For nuclei far from stability the differences in isobaric masses increases
quadratically and the binding energy of the last nucleon decreases dramatically
making beta-delayed particle emission the dominant decay channel at the drip lines.
Beta decay is a well understood process and allows for a wide variety of
spectroscopic information to be extracted from experiment: level energies,...

In this presentation, we show how nuclear ground state properties like spins,
magnetic dipole and electric quadrupole moments, and nuclear charge radii can
provide us with detailed information about the nuclear structure and how systematic
studies of these observable towards the driplines can help to test the validity of
newly developed nuclear models and interactions.
This will be...

Physics at the proton and neutron drip lines
Invited oral contribution
Our picture of the structure of nuclei is undergoing dramatic changes when systems
far away from the line of stability are studied. Established landmarks in the
nuclear landscape like the magic numbers are weakened or displaced, and the nuclear
spin-orbit interaction appears to diminish. In the most extreme nuclear systems that
can be experimentally studied today, various types of...

The position and even the existence of a neutron and a proton drip lines are among
the great, still unresolved, questions of nature.

will specialize on Nuclear Physics theoretical issues.

Like few other parameters, the mass of an atom, and its inherent connection with the
atomic and nuclear binding energy is a fundamental property, a unique fingerprint of
the atomic nucleus. Each nuclide comes with its own mass value different from all
others. For short-lived exotic atomic nuclei the importance of its mass ranges from
the verification of nuclear models to a test of the...

Precision measurements of correlation observables in nuclear
beta decay constitute a sensitive tool to search for signatures

After analysis by the HIP working group [CERN-AB-2004-022], the number of protons
that the existing accelerators can deliver after the year 2005 has been found to be

upon the LHC upgrade and the physics to be addressed....
