Investigation of the tensor analyzing power t20 in the reaction d→ + p → 3 He + η — •Michael Papenbrock, Christopher Fritzsch, Paul Goslawski, Alfons Khoukaz, Malte Mielke, Daniel Schröer, and Alexander Täschner — Westfälische Wilhelms-Universität, Münster, Germany
Previous measurements on the reaction d + p → 3He + η with the ANKE spectrometer at the COoler SYnchrotron - COSY - of the Forschungszentrum Jülich provided strong indications for the existence of a quasi-bound state of the η − 3He system. In order to gather more evidence for this possible quasi-bound state, measurements with a polarized deuteron beam have been performed at ANKE on the reaction d→ + p → 3He + η. Hence, the investigation of the energy dependence of the tensor analyzing power t20 allows to study in more detail the role of the final state interaction in the strong enhancement of the total cross section.
Recent results will be presented and discussed. Furthermore, a brief outlook on the upcoming measurement on the reaction p + n → d + η in the context of η-mesic nuclei will be given.
Supported by the COSY-FFE program.
