Coulomb Dissociation experiments with proton rich isotopes at LAND/R³B setup — •Christine Wimmer — Universität Frankfurt, Deutschland

After the implementation of the proton arm at the LAND/R³B setup at GSI in Darmstadt it is possible to extend the experimental programme to proton rich nuclei of astrophysical relevance. Coulomb dissociation induced reactions with secondary ion beams consisting of short-lived proton-rich isotopes produced at the fragment separator (FRS) have been investigated. This contribution offers an overview over the application of this method to determine (p, γ) cross sections from (γ, p) reactions and presents analysis strategies at the example of the ²⁷Si(γ, p)²⁶P experiment.
