Abstract

The tensor analyzing power $T_{20}$ for the radiative capture reaction ${}^{1}H (d_{pol}, γ) {}^{3}{He}$ has been measured in order to test new three-body wave functions. This observable arises from the $D$ state of ${}^{3}{He}$ . An effective two-body direct-capture calculation, which was previously shown to fit the $a_{2}$ coefficient of a Legendre-polynomial expansion of the differential cross section, is found to give a good description of the present data. A value for the asymptotic $\frac{D}{S}$ ratio is extracted from the data although it is found to be model dependent.
