Abstract
A quantum mechanical picture, relating accelerated geodesic
deviation to creation of massive particles via quantum tunneling in curved
background spacetimes, is presented. The effect is analogous to pair
production by an electric field and leads naturally to production of massive
particles in de Sitter and superluminal FRW spacetimes. The probability of
particle production in de Sitter space per unit volume and time is computed
in a leading semiclassical approximation and shown to coincide with the
previously obtained expression.
