Polarization Differences in the ReactionsD(d,p)TandD(d,n)He3and Charge Symmetry

Accurate measurements have been made of the analyzing power for the reaction $\mathrm{T}\mathrm{}(p,d)\mathrm{}\mathrm{D}$ which are equivalent to proton polarizations from $\mathrm{D}\mathrm{}(d,p)\mathrm{}\mathrm{T}$. If allowance is made for the reaction $Q$-value difference between $\mathrm{D}\mathrm{}(d,p)\mathrm{}\mathrm{T}$ and $\mathrm{D}\mathrm{}(d,n)\mathrm{}{}_{}{}^3{}_{}{}^{}\mathrm{He}$, thus comparing the data at the same outgoing neutron and proton energies, the polarizations are identical. This agreement eliminates much of the concern about charge-symmetry violation in the $d+d$ reactions.
