Scientific paper

We study inhomogeneous multidimensional cosmological models with a higher
dimensional space-time manifold under dimensional reduction and show that small
inhomogeneous excitations of the scale factors of the internal spaces near
minima of effective potentials should be observable as massive scalar particles
(gravitational excitons) in the external space-time.
