Polarization transfer in ($\overrightarrow{d}$,$\overrightarrow{n}$) reactions on light nuclei at $\theta =0\mathrm{}°$

Transverse vector polarization transfer coefficients $K_y^{y^{\prime }}$ have been measured at a reaction angle of 0° for the processes ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$($d$,$n$)${}_{}{}^{13}{}_{}{}^{}\mathrm{N}$, ${}_{}{}^{14}{}_{}{}^{}\mathrm{N}$($d$,$n$)${}_{}{}^{15}{}_{}{}^{}\mathrm{O}$, ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$($d$,$n$)${}_{}{}^{17}{}_{}{}^{}\mathrm{F}$, and ${}_{}{}^{28}{}_{}{}^{}\mathrm{Si}$($d$,$n$)${}_{}{}^{29}{}_{}{}^{}\mathrm{P}$. The deuteron beam energy ranged from about 5 to 15 MeV for most cases. For the ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$($d$,$n$)${}_{}{}^{13}{}_{}{}^{}\mathrm{N}$ reaction an excitation function of the differential cross section at 0° also was obtained from 6 to 14 MeV for the ground state and first excited state transitions. The polarization transfer coefficients were all positive and typically just slightly lower than the value of $\frac{2}{3}$. This indicates that the contribution from spin transfer $s=\frac{3}{2}$ is small at 0°. Theoretical predictions of $K_y^{y^{\prime }}$ (0°) using the distorted-wave Born approximation agree with the data to within about 10%.
