Investigation of different normalization reactions for dp collisions at ANKE* — •Christopher Fritzsch, Daniel Guderian, Malte Mielke, Michael Papenbrock, Daniel Schröer, and Alfons Khoukaz — Institut für Kernphysik, WestfälischeWilhelms-Universität Münster, Germany

1em Studies on the total cross sections of the reaction d+p3He+η are of special interest since they differ strongly from a pure phase space behaviour near threshold. This behaviour could be an indication for the presence of a quasi bound state of the η3He-system. New high precision data from the ANKE spectrometer at the accelerator ring COSY at the Forschungszentrum Jülich allow the extraction of precise total and differential cross section values for the η production up to an excess energy of Q= 15 MeV. Therefore, a careful luminosity determination was realized via dp-elastic scattering for 18 beam momenta in a range between 3120.17 MeV/cpd ≤ 3204.16 MeV/c. Furthermore, to verify the results of the dp-elastic scattering an independent normalization channel d+pd0+pspec was used. The method and recent results for both channels will be presented and discussed.
