Angular distributions of the analyzing power, polarization function, and polarization transfer coefficient $K_y^{y^{\prime }}$ at $E_t=10.5\mathrm{}$ MeV for the ${}_{}{}^2{}_{}{}^{}\mathrm{H}(t,n){}_{}{}^4{}_{}{}^{}\mathrm{He}$ reaction have been measured. In addition, $K_y^{y^{\prime }}\left(0\mathrm{}°\right)$ data for energies between 6 and 14 MeV have been obtained. Both neutron and charged particle detection were used in these measurements. Also, an angular distribution of the analyzing power for the elastic scattering process ${}_{}{}^2{}_{}{}^{}\mathrm{H}(t,t){}_{}{}^2{}_{}{}^{}\mathrm{H}$ at 10.5 MeV is presented. Comparisons with predictions of an $R$-matrix analysis of the five-nucleon system are included.
