In November 2010, the search for the 4He-η bound state was performed with high statistics and high acceptance with the WASA-at-COSY facility using a ramped beam technique. The signature of η - mesic nuclei is searched for in the measured excitation functions for the two reaction channels: dd → 3Henπ0 and dd → 3Hepπ− near the η production threshold. This report includes the description of the experimental method and the status of the data analysis.
