Longitudinal polarization-transfer coefficients for the ${}^{3}\mathrm{H}(\stackrel{\ensuremath{\rightarrow}}{p},\stackrel{\ensuremath{\rightarrow}}{n}{)}^{3}\mathrm{He}$ reaction have been measured at zero degrees for proton energies of 1.3--2.8 MeV. The results show a striking resonance behavior for energies corresponding to excitation of the ${0}^{\ensuremath{-}}$ level in ${}^{4}\mathrm{He}$ at 21.0 MeV. In agreement with $R$-matrix calculations, the value approaches unity at 1.52 MeV, the peak of the resonance. Near this same energy, at 1.62 MeV, the transverse polarization-transfer coefficient was measured to be consistent with zero.
