Investigation of the 3He η Final State in dp-Reactions at ANKE — •Tobias Rausmann, Paul Goslawski, Alfons Khoukaz, Timo Mersmann, Malte Mielke, Michael Papenbrock, and Alexander Täschner — Institut für Kernphysik, Westfälische Wilhelms-Universität, Münster, Germany
The reaction d+p→3He+η has been investigated at the ANKE spectrometer with high precision in a ramped beam near threshold and at higher excess energies of Q = 20, 40 and 60 MeV. This kind of experiment is important for the open question of existance/non existance of η-mesic nuclei, which would be formed in the bound system. The ANKE spectrometer has a full geometrical acceptance and therefore high statistic data on this reaction have been obtained. Total and differential cross sections have been determined to investigate the final state interaction and contributions from higher partial waves. The results of these measurements at higher energies will be presented and compared with the results near threshold and from previous experiments at similiar energies.
