The reaction dp →3He η has been investigated at the COSY-ANKE experiment with both an unpolarised and a vector/tensor polarised deuteron beam in an excess energy range of Q = 0 MeV up to Q = 10 MeV. The determination of the tensor analysing power t20 along with the unpolarised cross section allows for the investigation of the s-wave production amplitudes near threshold. The weak energy dependence of t20 supports a strong final state interaction of the η 3He system which might lead to a quasi-bound η-mesic state. Furthermore, the angular dependence of the t20 might reveal further insight into the production amplitude.
