Abstract
Using a perturbation expansion to second order in a quantity determining deviation from conformal invariance the authors obtain general expressions for the number and energy densities at late times of free, massive, scalar particles produced by quantum effects in an anisotropic space-time. Some interesting special cases are given and cosmological implications discussed.Keywords
