Phys. Rev. D 62, 072004 (2000) [8 pages]Cross sections for deuterium, tritium, and helium production in p̅ p collisions at √s=1.8 TeVReceived 10 February 2000; published 8 September 2000 We present the results of a search for the production of light elements in p̅ 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. © 2000 The American Physical Society URL:
