The $\mathrm{D}\mathrm{}(d,p)\mathrm{}\mathrm{T}$ reaction cross section has been measured by two methods using ${\mathrm{D}}_2$O ice targets. For $E_d$ from 206 to 516 kev, a double-focusing magnetic spectrometer was used to obtain the momentum spectrum of the protons and tritons, from which the reaction cross section can be determined. For $E_d$ from 35 to 550 kev, the proton yield from a thick target was differentiated to obtain the cross section. Both thin and thick target methods were used to measure the angular distribution over the energy range $E_d$ from 35 to 550 kev. The angular distribution is expressed in terms of a Legendre polynomial expansion. Various sources of experimental error are considered and the probable error of the total cross section is found to be ±5 percent.
