Experimental study of the 15O(2p, γ)17Ne cross section by Coulomb Dissociation for the rp process
2013
The time-reversed reaction 15O(2p, $\gamma$)17Ne has been studied by the Coulomb
dissociation technique. Secondary 17Ne ion beams at 500 AMeV have been produced by
fragmentation reactions of 20Ne in a beryllium production target and dissociated on a secondary
Pb target. The incoming beam and the reaction products have been identified with the
kinematically complete LAND-R3B experimental setup at GSI. The excitation energy prior to
decay has been reconstructed by using the invariant-mass method. The preliminary differential
and integral Coulomb Dissociation cross sections ($\sigma$Coul) have been calculated, which provide a
photoabsorption ("photo) and a radiative capture cross section ($\sigma$cap). Additionally, important
information about the nuclear structure of the 17Ne nucleus will be obtained. The analysis is
in progress.
