Angular distributions of tHe tensor analyzing powers A{sub zz} and A{sub zz} - A{sub yy} have been measured for the fusion reactions D(d,p){sup 3}H and D(d,n){sup 3}H at incident deuteron energies of 25, 40, 60, and 80 keV. Precise measurements of these observables are necessary to reveal the mechanisms which govern these complex charge-symmetric reactions, to indicate the effect of polarization on fusion rection rates, and to provide additional information for an on-going global analysis of the energy levels of {sup 4}He. To collect these data, which are among the lowest energy analyzing powers ever measured, a low energy beam facility was constructed, novel thin film deuterated targets were fabricated, and a deuteron tensor polarimeter was designed and calibrated. The data indicate that entrance quintet S waves are important for these reactions, and that the use of polarized fuel would not produce an aneutronic fusion reactor. These analyzing power distributions are compared to other recent data at low energies, to R-matrix predictions made without these data, and to a global R-matrix parametrization which includes these data.
