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