1. The Youngsters in Theoretical Nuclear Physics An Ace up France’s sleeve in the RIB competition

2. Some Thoughts for the Future The European Roadmap : FAIR and EURISOL For What Science? How can theoreticians, and particularly young French theoreticians, maximize their contribution?

3. NuPECC recommends the construction of 2 ‘next generation’ RIB infrastructures in Europe, i.e. one ISOL and one in-flight facility. The in-flight machine would arise from a major upgrade of the current GSI facility: FAIR, while EURISOL would constitute the new ISOL facility THE EUROPEAN PLAN The EURISOL Road Map Vigorous scientific exploitation of current ISOL facilities : EXCYT, Louvain, REX/ISOLDE, SPIRAL Construction of intermediate generation facilities: SPIRAL2, HIE- ISOLDE, SPES Design and prototyping of the most specific and challenging parts of EURISOL in the framework of EURISOL_DS.

9. The Major Challenge is… That each of these facilities will cost 1 Billion (10 9 ) € to build and about 100 M€ each year to run We need to convince ourselves, our pairs, our funding agencies and eventually the tax payers that this is good use of the money spent!

14. Neutron-proton pairing and correlations n-p pairing can occur in 2 different states: T=0 and T=1. The former is unique to n-p. It can be best studied in N=Z nuclei through spectroscopy and 2-nucleon transfer reactions. Beyond the mean field

19. A stimulating workshop A pleasure to listen to wonderfully talented young (and slightly older) theoreticians and experimentalists. This young theory community is unique to the world and an asset to France and Europe in the RIB competition. Good collaboration between groups Understanding of the necessity of close collaboration with experimenters.

20. A somewhat restricted view… World champions in mean field and beyond but Shell model? Ab-initio calculations? Reactions? Applications? Your community is large enough to master several approaches Your work should be driven by the diversity and advancement of the field, and not by the history of your lab.

21. Some tentative advice…maybe Improve your models and their predictive power based on new data but Take some time to think about new concepts, this will keep our field moving Get out of your lab. Go abroad and initiate collaborations. Spend some time in accelerator labs. See the World (of nuclear physics) Collaborate on experiments from submission to interpretation. Feel responsible. Help plan the future. Give you input and time to help foster new facilities. (Join the EURISOL User group at www.eurisol.org)
