Study of the ¹⁵o(2p, γ)¹⁷Ne cross section by coulomb dissociation of ¹⁷Ne for the rp process of nucleosynthesis

The 15o(2p, γ)17Ne cross section has been studied by the inverse reaction, the Coulomb dissociation of 17Ne. The experiment has been performed at the GSI. The 17Ne excitation energy prior to decay has been reconstructed by using the invariant-mass method. The preliminary differential and integral Coulomb dissociation cross sections (σCoul) have been extracted, which provide a photoabsorption (σphoto) and a radiative capture cross section (σcap). Additionally, important information about the 17Ne nuclear structure will be obtained. The analysis is in progress.
