The differential cross section for the scattering of protons by tritons has been measured in the angular range of 41.85^∘{} to 163^∘{} in the laboratory (54.7^∘{} to 168.7^∘{} in the center-of-mass system) at five energies between 2.54 and 3.50 Mev using protons from the Minnesota electrostatic generator. A small volume (42 cc) scattering chamber with an angular range of 17^∘{} to 163^∘{} was used for these measurements. Measurements of proton-proton and proton-helium cross sections and a comparison of the results with those obtained previously with a large scattering chamber showed that this small chamber gave results too high (about 3 percent) at the low scattering angles. These measurements determined a correction which was applied in the calculation of the p-T cross sections from the experimental data. The center-of-mass differential cross section varies between a maximum of 0.243×{}10^-24 cm² per unit solid angle at 54.7^∘{} and 3.5 Mev and a minimum of 0.065×{}10^-24 cm² per unit solid angle at 109.5^∘{} and 3.5 Mev in the angle and energy range studied. The cross sections considered as a function of angle display a strong minimum, near 100^∘{}, in the center-of-mass coordinate system. The cross section for a given angle is a slowly varying function of energy.
