  A complete set of analyzing powers for the dd->3Hp reaction at the kinetic
beam energy of 200 MeV has been measured in the full angular range in the c.m.
frame. The observed signs of the tensor analyzing powers Ayy, Axx, and Axz at
forward and backward directions have clearly demonstrated the sensitivity to
the ratio of the D- and S-wave components of the triton and deuteron,
respectively. The new high-precision data are compared with the prediction of
the relativistic multiple-scattering model by using standard wave functions of
the three-nucleon bound state and of the deuteron.
