The data on the tensor Ayy, Axx, Axz and vector Ay analyzing powers in the dd → 3Hen obtained at T d = 270 MeV in the angular range 0° - 110 ° in the c.m. are presented. The observed negative sign of the tensor analyzing powers Ayy, Axx and Axz at small angles clearly demonstrate the sensitivity to the ratio of the D - and S -wave component of the 3He wave function. However, the one-nucleon exchange calculations by using the standard 3He wave functions have failed to reproduce the strong variation of the tensor analyzing powers as a function of the angle in the c.m.
