Phys. Rev. Lett. 39, 1373–1376 (1977)Effective-Potential Approach to Graviton Production in the Early UniverseReceived 16 June 1977; published in the issue dated 28 November 1977 The production of gravitons in a homogeneous, isotropic, spatially flat universe containing radiation and a small admixture of cold baryons is studied by an effective-potential method which takes into account the back reaction of the produced gravitons on the geometry. The total probability per unit volume to produce a pair of gravitons is finite and has a very small value for a universe with parameters corresponding to my own. © 1977 The American Physical Society URL:
