Cross sections for deuterium, tritium, and helium production in (p)over-barp collisions at √s=1.8 TeV -: art. no. 072004

We present the results of a search for the production of Light elements in (p) over bar p collisions at the Fermilab Tevatron collider. Momentum, time of flight, and dE/dx measurements are used to distinguish nuclei from elementary particles. A production ratio for deuterium to hydrogen is calculated and compared to the primordial value of the big bang model. Some evidence for tritium is found and none for helium isotopes.
