Pair production of free scalar particles in a spatially-flat Robertson-Walker spacetime with cosmic scale factors a(t)=ao cosh(at) and a(t)=ao sin(at), that represent an open and a closed universe, respectively, is investigated. The amplitude of pair production was determined by considering the prop...
