The polarization of neutrons from the source reaction $\mathrm{T}(d, n){\mathrm{He}}^{4}$ has been measured at laboratory angles of 30\ifmmode^\circ\else\textdegree\fi{} and 90\ifmmode^\circ\else\textdegree\fi{} over the range of deuteron energy ${E}_{d}$, from 0.1 to 7.7 Mev. In addition, at ${E}_{d}=5$ Mev an angular distribution of the polarization was measured. The polarization, which is small at low energies, at ${E}_{d}=7.7$ Mev attains values of +0.64 and -0.52 at 30\ifmmode^\circ\else\textdegree\fi{} and 90\ifmmode^\circ\else\textdegree\fi{}, respectively. The Basel sign convention is used. The polarization was analyzed by means of a liquid helium scintillator used in coincidence with a plastic scintillator.
