Coulomb dissociation reactions on Mo isotopes for astrophysics applications

Abstract

Coulomb excitation cross sections on the stable 92,94,100Mo and unstable 93Mo isotopes were measured at the SIS/FRS/LAND facility at GSI, Darmstadt. Experimental data on these isotopes are important to explain the problem of the underproduction of 92Mo and 96Ru in all existing models of p-process nucleosynthesis. Preliminary integral cross sections for 100Mo(γ ,n)99Mo, 100Mo(γ ,2n)98Mo and 92Mo(γ ,n)91Mo reactions are presented. To verify the accuracy of the method, the results for the stable isotopes will be compared to the measurements with bremsstrahlung photons done at S-DALINAC (TU Darmstadt) and ELBE (FZ Dresden-Rossendorf). © Copyright owned by the author(s).
