Abstract
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.Keywords
