Abstract

Understanding of the production processes of the η meson will strongly rely on the precise determination of spin observables. So far these observables have been determined only for few excess energies and with low statistics Winter et al. Eur. Phys. J. A18 , 355 2003; Czyzykiewicz et al. Phys. Rev. Lett. 98 , 122003 2007; Balestra et al. Phys. Rev. C69 , 064003 2004. In the year 2010 WASA detector was used for the measurement of the \\overrightarrow {p}p ightarrow pp\eta \ reaction with the polarized proton beam of COSY Moskal and Hodana J. Phys. Conf. Ser 295 , 012080 2011. The measurement was done for the excess energy of Q = 15 MeV and Q = 72 MeV. In total about 10 events corresponding to the \\overrightarrow {p}p ightarrow pp\eta \ reaction have been collected.
