Direct measurement of the 96Ru(p,γ)97Rh capture cross section — •Meiko Volknandt1, Markus Reich1, René Reifarth1, Jan Glorius2, Yuri Litvinov2, Michael Wiescher3, Joachim Goerres3, and Edward Stech3 — 1Goethe Universität, Frankfurt, Germany — 2GSI, Darmstadt, Germany — 3University of Notre Dame, Notre Dame, USA
Comparing the solar abundances of 96Ru to theoretical p-process calculations shows a large underproduction of the nucleus in the models. Therefore the nuclear data input needs to be constrained by experiments.
In 2015, a proof-of-principle experiment was performed at the experimental storage ring ESR at GSI, Darmstadt, where the reaction cross section of the reaction 96Ru(p,γ)97Rh has been measured in inverse kinematics at energies between 9 and 11 MeV.
To verify this method, an activation experiment was performed at the Instutute for Structure and Nuclear Astrophysics at Notre Dame, USA.
The 96Ru(p,γ)97Rh cross section has been directly measured at 3 MeV to compare with a previous activation experiment as well as between 9 and 11 MeV. An overview of the experiment as well as the preliminary results is presented.
