Abstract

The quantized scalar field with arbitrary coupling in a nonstationary isotropic gravitational field evolving between two singularities is investigated. The number of pairs created from vacuum is demonstrated to have a very drastic dependence on the value of the coupling coefficient ξ. In other words the vacuum quantum effects of nonconformal field may be important in the early cosmology.
