Nuclear reactions can be understood as exposing nuclei to external fields, Coulomb or nuclear. ENSAR-2 exotic beam facilities (ISOLDE, GANIL and GSI-FAIR) provide different time scales for the external fields, associated to the collision time. The complementarity of these measurements will be discussed. Astrophysically relevant reaction rates in stellar environments imply averages over...
.The capabilities of HIE-ISOLDE are well matched to a broad range of experimental nuclear astrophysics studies. In this talk I will review recent works relevant to x-ray bursts and core collapse supernovae, and will present some of the proposals in these and other areas presently awaiting beam time.
.Understanding energy production and nucleosynthesis in stars requires a precise knowledge of the nuclear reaction rates at the energies of interest. To overcome the experimental difficulties arising from the small cross sections at those energies and from the presence of the electron screening, the Trojan Horse Method has been introduced. The method represents one of the most powerful tools...
.Some of the questions in nuclear physics for astrophysics and the news on methods we use in the laboratory to answer them will be reviewed, with emphasis on what the new large experimental facilities can bring.
Also will discuss about NUSPRASEN’s planned activities for nuclear astrophysics.
.Exotic nuclei play an important role in many astrophysical
environments, in particular the collase of massive stars and
r-proccess nucleosynthesis. During the collapse, the composition of
the core is dominated by intermediate mass neutron-rich nuclei. Due to
the high temperatures and densities, electrons can be captured on
nuclei removing the major source of pressure support and...
