Observation of the DeuteronD-State Effects in (d, p) Reactions

Angular distributions of the three tensor analyzing powers have been measured for ($d, p$) reactions on ${}_{}{}^{52}{}_{}{}^{}\mathrm{Cr}$, ${}_{}{}^{90}{}_{}{}^{}\mathrm{Zr}$, and ${}_{}{}^{208}{}_{}{}^{}\mathrm{Pb}$. Distorted-wave calculations are inconsistent with the measurements if the deuteron $D$ state is ignored. However, excellent agreement is obtained when the effects of the $D$ state are included. We discuss the dependence of the tensor analyzing powers on incident deuteron energy, $Q$ value, and angular momentum transfer.
