The workshop brought together the TNET nuclear structure and reactions theorists, with a track record of collaborative activity, plus students. A number of young European scientists presently working overseas also participated.

The aims of the Workshop were primarily:

(1) To share knowledge and foster further research collaboration on topical problems in nuclear reactions, structures, and their interface,

(2) To review most recent theoretical advances and understanding, as driven by new experimental capabilities,

(3) To give exposure to the state-of-the-art theoretical tools and of open questions to young scientists, and to foster younger researcher networking,

(4) To allow assessment of priorities concerning reaction theory and the reactions and structures interface as input into integrated theory themes in FP7.

Main themes identified for the Workshop were:

* Correlations in nuclei: their role, treatment and observation

* Novel reaction methodologies: approaches and new technologies

* Novel phenomena in the study of nuclei far from stability

* Few- and many-body methods, status, opportunities and limitations

* Experimental and theoretical reaction capabilities at new facilities

* Break-up and transfer reaction methods and spectroscopy

* Structure models at the interface with the continuum

* Priorities, future directions and (FP7) opportunities

The detailed programme of the workshop is given in Annex 1 and on the TNET website. The workshop talks (as pdf files) can be browsed from the TNET webpage http://www.nucleartheory.net/tnet/presentations.htm. A complete list of participants and a summary of the workshop are also given in Annex 1.

3. Summary of the Workshop, by the Coordinator

The workshop was able to review advances and allow discussion of open questions for a considerable range of theoretical work within and in collaboration with TNET partners. The instructions to discussion leaders was to review the current status, the underpinning theoretical methodologies, open problems and future opportunities. The resulting presentations and extensive discussions were effective in touching each of these bases.

Recent advances and future possibilities were revealed at the Workshop. The major methodologies, underpinning physics, and challenges to advances in direct

nuclear reactions, few-body, (ab-initio) many-body and time-dependent approaches were presented. A particular advance is the practical solution of the Faddeev/AGS equations for few-body dynamical systems in the presence of Coulomb and complex effective interactions, that is permitting assessments of the accuracy of other approximate dynamical theories of break-up and transfer reactions. The enormous efficiency gains resulting from the implementation of the J-scheme within the coupled-cluster approach is also allowing calculations of ground states of medium mass nuclei, to confront experiment. New GSI and NSCL measurements that link strongly with several of the theoretical activities under discussion were presented and stimulated much interest. These included data for nucleon knockout reactions that reveal intriguing differences in residue yields when using a nuclear and a nucleon target. The participation of young European-trained scientists (presently working overseas), Drs J Rotureau, G Hagen (ORNL), Quaglione (LLNL) and Rios Huguet (NSCL) strengthened emerging and fostered new collaborative opportunities.

The workshop was of immense value in both disseminating recent theoretical advances and in setting out clearly the theoretical foundations of the methodologies used. A number of ongoing collaborations were enlivened and new ones stimulated, by new results, data and theory capabilities. These included, at the time of the workshop, Sevilla-Surrey, Lisboa-Surrey-GSI, ORNL-Trento, GANIL-ORNL, Sevilla-Surrey-NSCL, Brussels-Surrey, Bergen-ORNL, and Lisboa-Sevilla-Surrey joint activities. Fonseca, Ploszajczak, Gomez-Camacho and Tostevin were able to coordinate final input and manpower priorities toward the FP7 ENSAR proposal and discuss future network activity with the ECT*.
