Abstract
The non-perturbative method, developed recently, of WKB approximation in complex time is applied to some known curved space time. Three case s namely (1) static in and out region, (2) non-static in and out regio n, (3) static in and non static out region are considered here. We fin d non-trivial particle production corresponding to the quantum vacuum definition of Castagnino and Mazzitelli.
