Stable beam Experiments
-Charged particle induced reactions (G. Gyurky)
Quiescent burning: H and He induced reactions on
stable isotopes (almost always). We are far from a the full
understanding.
-Fusion reactions of astrophysics interest within the
STELLA project
-p-process: cross sections measurements with charged
particles
-Direct and inverse kinematics measurements @ SPIRAL2

• Conveners to produce zeroth draft of document
• Recommendations include (not complete and in no particular
order)
•
•
•
•
•
•
•
•
•
Better coordination of European activity, including but not limited to
networking – European Virtual Institute?
Interdisciplinary and technical training
Improve visibility of field of nuclear astrophysics
Coordination of smaller laboratory facilities and activities
Coordinated beamtime campaigns at large facilities
Support for “aging” but important equipment and facilities
Complete next generation RIB facilities
Continuing need for sensitivity studies to direct experimental focus
Connection of ab-initio methods to DFT approaches
