Measurement of A_zz of pd radiative capture at E_d=196MeV

In our previous measurement of pd radiative capture at E_d = 137 and 196MeV, we found an interesting fact that the measured tensor analyzing powers show the relation A_xx ≈ A_yy, although calculated A_xx and A_yy are apparently different, A_xx ≠ A_yy. The measured A_yy agrees fairly well with the 3N calculations, and the measured A_xx largely disagrees with calculated A_xx. Similar experiments on pd capture have been made at KVI at nearly the same energies of 130-180MeV. The KVI data also support A_xx ≈ A_yy relation, but absolute values of A_xx and A_yy at KVI are about half of RCNP data. Therefore, we made a new experiment of pd capture at E_d =196MeV. A_zz was measured in three different ways, and data analysis is in progress. Preliminary data seem to support our previous data.
