Measurements at the experiment COSY-11 at the synchrotron COSY in the Research Centre Jülich prioritise studier of near threshold meson production in nucleon- nucleon collisions. Due to the high momentum transfer between the baryons involved such experiments are sensitive an small distances and the relevant interactions in these regions. Experiments an meson production therefore enable to understand the fundamental hadronic interaction and the underlying reaction mechanisms. A study of the influence of higher partial waves succeeds with polarisation observables which are sensible thereon. The analysing power represents besides the spin correlation coefficients one of these measurands. For its determination the polarisation of one of the two colliding particles is necessary. First results of the analysing power are presented using data in the reaction $\overrightarrow{p}$p $\rightarrow$ pp$\eta$ taken at the experiment facility COSY-11 with a beam momentum P$_{beam}$ = 2.096 GeV/c according to an excess energy Q = 40 MeV. A selection of the pp$\eta$ final-state is done via a kinematical complete reconstruction of this three body system. The determination of the relative luminosity of both spin states is based an the simultaneous measurement of the elastic proton-proton scattering. Individual interference terms of amplitudes of partial waves were determined and enables a comparison with theoretical forecasts. |
