Nucleosynthesis

Nuclear Equation of state (EoS) p V T pV = nRT SOFT HARD E ( ,I) = E ( ,0) + E sym (  )I 2 + o (I 4 ) +... I = (  n −  p ) /  E sym (  ) ≈ E(  ) neutr. matter - E(  ) sym. nucl. matter

Symmetry energy The asymmetry term contributes a greater uncertainty than does the symmetric matter EOS. (Bao-An Li) Z. Xiao et al., PRL 102 (2009)

How ? GDR & PYGNY RESONANCE

 Creation of discussion fora: What for ? - new intensive RIB facilities - train up a new generation of scientists to take over leadership  Open character  Exchange of students & experts  Facilitate a global dimension (complementarities)  Timely initiative  Prepare future - theoreticians – experimentalists - nuclear physics – astrophysics
