Determination of the Asymptotic Ratio of the DeuteronD- andS-State Amplitudes

The value 0.026 49±0.000 43 is deduced for the deuteron asymptotic $D$- to $S$-state ratio from measurements of the ${}_{}{}^{208}{}_{}{}^{}\mathrm{Pb}$($d$,$p$)${}_{}{}^{209}{}_{}{}^{}\mathrm{Pb}$ tensor analyzing powers at sub-Coulomb bombarding energies $E_d=7, 8, \mathrm{and} 9$ MeV. The quoted uncertainty includes statistical errors, beam-polarization measurement errors, and systematic errors which result from a choice of optical-model parameters used to describe the reaction. The result is compared to several theoretical deuteron wave functions.
