Abstract

The data on the vector Ay and tensor Ayy, A xx, Axz analyzing powers for the \overrightarrow dd \to 3\!\!Hp and \overrightarrow dd \to 3\!\!Hen reactions at Ed = 200 and 270 MeV are presented. The data demonstrate large values of analyzing powers and their strong variation versus the scattering angle. The observed negative sign of the tensor analyzing powers for these reactions at small angles clearly demonstrate the sensitivity to the D/S ratio of the 3H and 3He wave functions, respectively. The calculations performed within one-nucleon exchange model with the use of the standard three-nucleon bound state wave functions fail to reproduce the data on the tensor analyzing powers.
