STUDY OF THE 15O(2p, γ) 17 Ne CROSS SECTION BY COULOMB DISSOCIATION OF 15Ne 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 (σ_Coul) have been extracted, which provide a photoabsorption (σ_photo) and a radiative capture cross section (σ_cap). Additionally, important information about the ¹⁷Ne nuclear structure will be obtained. The analysis is in progress. [ABSTRACT FROM AUTHOR]
