(d,α) reaction and theαparticleDstate

The recent suggestion that the effects of a $D$-state component of the $\alpha$ particle are being seen in (d,$\alpha$) reaction tensor analyzing power data is reexamined using exact finite range distorted-wave Born approximation calculations. Results for ${}_{}{}^{32}{}_{}{}^{}\mathrm{S}(\mathrm{d}, \alpha ){}_{}{}^{30}{}_{}{}^{}\mathrm{P}(\mathrm{g}.\mathrm{s}.\mathrm{})$, at $E=16\mathrm{}$ MeV, are at considerable variance with two-nucleon-core relative motion amplitudes derived from shell model calculations.
