We report measurements of the invariant cross sections for production of deuterons and antideuterons with transverse momenta in the range 0.46 less than or equal top/sub perpendicular/less than or equal to3.89 GeV/c in collisions of protons with protons and with the nuclei of Be, Cu, and Pb at 70 GeV. The cross-section ratios sigma/sub d//sigma/sub p/ and sigma/sub d-bar//sigma/sub p-bar/ are given. We also have obtained data on the yields of tritium nuclei. An analysis shows that the production of deuterons, antideuterons, and tritium nuclei with large p/sub perpendicular/ is described by the model of fusion of secondary nucleons (antinucleons) with small relative momentum. A comparison is made with data obtained at a higher energy.
