abstract in english:	We search for an evidence of η-mesic He with the WASA detector. Two dedicated experiments were performed at the Cooler Synchrotron COSY-Jülich. The experimental method is based on the measurement of the excitation functions for the two reaction channels: dd \rightarrow ^{3}He p\pi ^{-} and dd \rightarrow ^{3}He n\pi ^{0}, where the outgoing N–\pi pairs originate from the conversion of the \eta meson on a nucleon inside the He nucleus. In this contribution, the experimental method is shortly described and the current status of the analysis is presented.
