Nuclear halo states have been found in a number of light nuclei close to the nucleon drip lines. These show a threshold phenomenon when a low separation energy allows the weakly bound nucleon (or cluster of nucleons) to tunnel into the space surrounding the nuclear core to give a large nuclear radius. In this very open structure, simple few-body or cluster models largely account for the most general properties of the halo states. The analysis of these threshold phenomena has important general consequences for low-energy reaction rates in nuclear astrophysics.
Experimental information of halo states has now been obtained from more precise breakup and particle transfer reactions, and these have provided new details that challenge both halo structure models and theories of reaction dynamics. This has supplemented the traditional measurements of size, of momentum distributions of fragments, and of beta decays to or from halo states. New developments in the precision of breakup and transfer theories have lead to continuing revisions of our views of halo structures, and such theories will soon contribute to the most reliable probes of halo nuclei.
It is clearly increasingly necessary to combine modern theoretical capabilities with detailed and accurately-specified experimental observations. The aim of the planned workshop is therefore to gather theorists, and experimentalists with a flair for theory, to take the measure of current and future progress in this field.
This workshop would be the natural followup of the previous workshop help in 1996 with the same title and the same organisers. This was judged by both the theory and experimental participants to provide a most instructive and fruitful meeting ground for the detailed discussion of all the necessary issues. Since much will have developed in the intervening five years, a successor workshop should prove similarly beneficial.
This meeting runs continuously after another workshop "Current theoretical and and experimental investigations of the nuclear many-body problem and applications", to be held 24 Sept - 3 Oct. See http://www.phy.ornl.gov/theory/dean/trento2/wpage.html The combined organisers intend to have, in the three-week period, a gradation from heavy nuclei to light nuclei to reactions.
