  The purpose of this work in to analyze particle creation in spaces with extra
dimensions. We consider, in particular, a massive scalar field propagating in a
Kaluza-Klein manifold subject to a constant electric field. We compute the rate
of particle creation from vacuum by using techniques rooted in the spectral
zeta function formalism. The results we obtain show explicitly how the presence
of the extra-dimensions and their specific geometric characteristics, influence
the rate at which pairs of particles and anti-particles are generated.
