The experiment on searching for η-mesic 3He nucleus was performed in May 2014 at COSY accelerator in Juelich by WASA-at-COSY Collaboration. The measurements were carried out using ramped beam technique which allows for the slow and continuous beam momentum change near the threshold of η meson creation. The luminosity was obtained based on pd → 3Heη reaction and quasielastic proton-proton scattering. The bound state of η-meson and 3He nucleus is searched for in pd → 3He2γ and pd → 3He6γ channels. The analysis is still in progress and the estimated upper limit value is on the level of few nanobarns.
